Academic Phrases for Writing Literature Review Section of a Research Paper

The literature review should clearly demonstrate that the author has a good knowledge of the research area. Literature review typically occupies one or two passages in the introduction section. A well-written literature review should provide a critical appraisal of previous studies related to the current research area rather than a simple summary of prior works. The author shouldn’t shy away from pointing out the shortcomings of previous works. However, criticising other’s work without any basis can weaken your paper. This is a perfect place to coin your research question and justify the need for such a study. It is also worth pointing out towards the end of the review that your study is unique and there is no direct literature addressing this issue. Add a few sentences about the significance of your research and how this will add value to the body of knowledge.

The literature review section of your research paper should include the following:

Previous literature
Limitations of previous research
Research questions
Research to be explored

There is a wide choice of __ available in the literature. This section reviews the literature related to __ It was reported in literature that __ A recent study by __ concluded that __ In the light of reported __ it is conceivable that __ The method introduced by __ has the advantage that __ One method employed by __ is __ A more comprehensive description can be found in __ For example, recent research suggests that __ This was successfully established as described by __ The author employed a __ methodology which prescribes the use of __

2. Limitations of previous research

A number of questions regarding __ remain to be addressed. A closer look to the literature on __, however, reveals a number of gaps and shortcomings.

Writing Articles & Reviews
December 27, 2023

A literature review is an essential part of any academic paper or research project. IT provides a comprehensive overview of the existing literature on a specific topic, identifies gaps in the current knowledge, and sets the context for the research to be conducted. Building a strong literature review requires careful selection of words and phrases to ensure that IT is well-structured, informative, and persuasive. In this article, we will discuss the words and phrases that are crucial for building a strong literature review.

Words and Phrases to Include in a Literature Review

1. “According to” – This phrase is commonly used to introduce evidence from scholarly sources. For example, “According to Smith (2016), the impact of climate change on biodiversity is a pressing concern.”

2. “ IT has been argued that” – This phrase is useful for presenting different viewpoints on a topic. For example, “ IT has been argued that technological advancements have both positive and negative effects on societal well-being.”

3. “Previous research has shown” – This phrase is effective for referencing existing studies that are relevant to the research topic. For example, “Previous research has shown a strong correlation between smoking and lung cancer.”

4. “A significant body of literature” – This phrase is used to indicate the volume and depth of existing research on a particular topic. For example, “A significant body of literature exists on the psychological impact of social media use.”

5. “In line with previous studies” – This phrase is used to establish continuity with existing research findings. For example, “In line with previous studies, our results indicate a positive association between exercise and mental health.”

6. “Key findings suggest” – This phrase is useful for summarizing the main conclusions of the literature review. For example, “Key findings suggest that mindfulness meditation can improve attention and cognitive performance.”

7. “ IT is evident that” – This phrase is used to emphasize the clarity or strength of evidence supporting a particular argument. For example, “ IT is evident that socioeconomic status has a profound impact on educational outcomes.”

8. “This is consistent with the findings of” – This phrase is used to demonstrate the alignment of the current research with existing literature. For example, “This is consistent with the findings of prior studies that have highlighted the importance of early childhood education.”

9. “Existing literature has identified” – This phrase is useful for highlighting specific issues or phenomena that have been documented in prior research. For example, “Existing literature has identified a range of factors that influence consumer purchasing behavior.”

10. “This study builds upon previous research by” – This phrase is used to emphasize the novelty or contribution of the current research. For example, “This study builds upon previous research by examining the long-term effects of climate change on coastal ecosystems.”

A strong literature review is essential for providing a solid foundation for any research endeavor. By incorporating the words and phrases discussed in this article, researchers can effectively convey the relevance, scope, and depth of the existing literature on their chosen topic. Careful selection and deployment of these words and phrases can enhance the clarity, coherence, and persuasiveness of the literature review, ultimately contributing to the overall strength and quality of the research project.

What is the purpose of a literature review?

A literature review serves several purposes, including providing an overview of existing research on a specific topic, identifying gaps in the current knowledge, and setting the context for a new research study. IT also helps to demonstrate the researcher’s familiarity with and understanding of the relevant literature in their field.

How do I structure a literature review?

A literature review typically follows a structured format, including an introduction, the body of the review (organized by themes or topics), and a conclusion. IT should present a coherent and logical argument, synthesizing and critically analyzing the existing literature on the chosen topic.

What are some common mistakes to avoid in a literature review?

Common mistakes in a literature review include focusing too much on summarizing individual studies without providing critical analysis, failing to clearly articulate the relevance of the literature to the research topic, and not including a sufficient variety of sources to support the argument being made. IT is also important to avoid presenting personal opinions without backing them up with evidence from the literature.

How to write a literature review introduction (+ examples)

The introduction to a literature review serves as your reader’s guide through your academic work and thought process. Explore the significance of literature review introductions in review papers, academic papers, essays, theses, and dissertations. We delve into the purpose and necessity of these introductions, explore the essential components of literature review introductions, and provide step-by-step guidance on how to craft your own, along with examples.

Why you need an introduction for a literature review

When you need an introduction for a literature review, what to include in a literature review introduction, examples of literature review introductions, steps to write your own literature review introduction.

A literature review is a comprehensive examination of the international academic literature concerning a particular topic. It involves summarizing published works, theories, and concepts while also highlighting gaps and offering critical reflections.

In academic writing , the introduction for a literature review is an indispensable component. Effective academic writing requires proper paragraph structuring to guide your reader through your argumentation. This includes providing an introduction to your literature review.

It is imperative to remember that you should never start sharing your findings abruptly. Even if there isn’t a dedicated introduction section .

Instead, you should always offer some form of introduction to orient the reader and clarify what they can expect.

There are three main scenarios in which you need an introduction for a literature review:

Academic literature review papers: When your literature review constitutes the entirety of an academic review paper, a more substantial introduction is necessary. This introduction should resemble the standard introduction found in regular academic papers.
Literature review section in an academic paper or essay: While this section tends to be brief, it’s important to precede the detailed literature review with a few introductory sentences. This helps orient the reader before delving into the literature itself.
Literature review chapter or section in your thesis/dissertation: Every thesis and dissertation includes a literature review component, which also requires a concise introduction to set the stage for the subsequent review.

It is crucial to customize the content and depth of your literature review introduction according to the specific format of your academic work.

In practical terms, this implies, for instance, that the introduction in an academic literature review paper, especially one derived from a systematic literature review , is quite comprehensive. Particularly compared to the rather brief one or two introductory sentences that are often found at the beginning of a literature review section in a standard academic paper. The introduction to the literature review chapter in a thesis or dissertation again adheres to different standards.

Here’s a structured breakdown based on length and the necessary information:

Academic literature review paper

The introduction of an academic literature review paper, which does not rely on empirical data, often necessitates a more extensive introduction than the brief literature review introductions typically found in empirical papers. It should encompass:

The research problem: Clearly articulate the problem or question that your literature review aims to address.
The research gap: Highlight the existing gaps, limitations, or unresolved aspects within the current body of literature related to the research problem.
The research relevance: Explain why the chosen research problem and its subsequent investigation through a literature review are significant and relevant in your academic field.
The literature review method: If applicable, describe the methodology employed in your literature review, especially if it is a systematic review or follows a specific research framework.
The main findings or insights of the literature review: Summarize the key discoveries, insights, or trends that have emerged from your comprehensive review of the literature.
The main argument of the literature review: Conclude the introduction by outlining the primary argument or statement that your literature review will substantiate, linking it to the research problem and relevance you’ve established.
Preview of the literature review’s structure: Offer a glimpse into the organization of the literature review paper, acting as a guide for the reader. This overview outlines the subsequent sections of the paper and provides an understanding of what to anticipate.

By addressing these elements, your introduction will provide a clear and structured overview of what readers can expect in your literature review paper.

Regular literature review section in an academic article or essay

Most academic articles or essays incorporate regular literature review sections, often placed after the introduction. These sections serve to establish a scholarly basis for the research or discussion within the paper.

In a standard 8000-word journal article, the literature review section typically spans between 750 and 1250 words. The first few sentences or the first paragraph within this section often serve as an introduction. It should encompass:

An introduction to the topic: When delving into the academic literature on a specific topic, it’s important to provide a smooth transition that aids the reader in comprehending why certain aspects will be discussed within your literature review.
The core argument: While literature review sections primarily synthesize the work of other scholars, they should consistently connect to your central argument. This central argument serves as the crux of your message or the key takeaway you want your readers to retain. By positioning it at the outset of the literature review section and systematically substantiating it with evidence, you not only enhance reader comprehension but also elevate overall readability. This primary argument can typically be distilled into 1-2 succinct sentences.

In some cases, you might include:

Methodology: Details about the methodology used, but only if your literature review employed a specialized method. If your approach involved a broader overview without a systematic methodology, you can omit this section, thereby conserving word count.

By addressing these elements, your introduction will effectively integrate your literature review into the broader context of your academic paper or essay. This will, in turn, assist your reader in seamlessly following your overarching line of argumentation.

Introduction to a literature review chapter in thesis or dissertation

The literature review typically constitutes a distinct chapter within a thesis or dissertation. Often, it is Chapter 2 of a thesis or dissertation.

Some students choose to incorporate a brief introductory section at the beginning of each chapter, including the literature review chapter. Alternatively, others opt to seamlessly integrate the introduction into the initial sentences of the literature review itself. Both approaches are acceptable, provided that you incorporate the following elements:

Purpose of the literature review and its relevance to the thesis/dissertation research: Explain the broader objectives of the literature review within the context of your research and how it contributes to your thesis or dissertation. Essentially, you’re telling the reader why this literature review is important and how it fits into the larger scope of your academic work.
Primary argument: Succinctly communicate what you aim to prove, explain, or explore through the review of existing literature. This statement helps guide the reader’s understanding of the review’s purpose and what to expect from it.
Preview of the literature review’s content: Provide a brief overview of the topics or themes that your literature review will cover. It’s like a roadmap for the reader, outlining the main areas of focus within the review. This preview can help the reader anticipate the structure and organization of your literature review.
Methodology: If your literature review involved a specific research method, such as a systematic review or meta-analysis, you should briefly describe that methodology. However, this is not always necessary, especially if your literature review is more of a narrative synthesis without a distinct research method.

By addressing these elements, your introduction will empower your literature review to play a pivotal role in your thesis or dissertation research. It will accomplish this by integrating your research into the broader academic literature and providing a solid theoretical foundation for your work.

Comprehending the art of crafting your own literature review introduction becomes significantly more accessible when you have concrete examples to examine. Here, you will find several examples that meet, or in most cases, adhere to the criteria described earlier.

Example 1: An effective introduction for an academic literature review paper

To begin, let’s delve into the introduction of an academic literature review paper. We will examine the paper “How does culture influence innovation? A systematic literature review”, which was published in 2018 in the journal Management Decision.

The entire introduction spans 611 words and is divided into five paragraphs. In this introduction, the authors accomplish the following:

In the first paragraph, the authors introduce the broader topic of the literature review, which focuses on innovation and its significance in the context of economic competition. They underscore the importance of this topic, highlighting its relevance for both researchers and policymakers.
In the second paragraph, the authors narrow down their focus to emphasize the specific role of culture in relation to innovation.
In the third paragraph, the authors identify research gaps, noting that existing studies are often fragmented and disconnected. They then emphasize the value of conducting a systematic literature review to enhance our understanding of the topic.
In the fourth paragraph, the authors introduce their specific objectives and explain how their insights can benefit other researchers and business practitioners.
In the fifth and final paragraph, the authors provide an overview of the paper’s organization and structure.

In summary, this introduction stands as a solid example. While the authors deviate from previewing their key findings (which is a common practice at least in the social sciences), they do effectively cover all the other previously mentioned points.

Example 2: An effective introduction to a literature review section in an academic paper

The second example represents a typical academic paper, encompassing not only a literature review section but also empirical data, a case study, and other elements. We will closely examine the introduction to the literature review section in the paper “The environmentalism of the subalterns: a case study of environmental activism in Eastern Kurdistan/Rojhelat”, which was published in 2021 in the journal Local Environment.

The paper begins with a general introduction and then proceeds to the literature review, designated by the authors as their conceptual framework. Of particular interest is the first paragraph of this conceptual framework, comprising 142 words across five sentences:

“ A peripheral and marginalised nationality within a multinational though-Persian dominated Iranian society, the Kurdish people of Iranian Kurdistan (a region referred by the Kurds as Rojhelat/Eastern Kurdi-stan) have since the early twentieth century been subject to multifaceted and systematic discriminatory and exclusionary state policy in Iran. This condition has left a population of 12–15 million Kurds in Iran suffering from structural inequalities, disenfranchisement and deprivation. Mismanagement of Kurdistan’s natural resources and the degradation of its natural environmental are among examples of this disenfranchisement. As asserted by Julian Agyeman (2005), structural inequalities that sustain the domination of political and economic elites often simultaneously result in environmental degradation, injustice and discrimination against subaltern communities. This study argues that the environmental struggle in Eastern Kurdistan can be asserted as a (sub)element of the Kurdish liberation movement in Iran. Conceptually this research is inspired by and has been conducted through the lens of ‘subalternity’ ” ( Hassaniyan, 2021, p. 931 ).

In this first paragraph, the author is doing the following:

The author contextualises the research
The author links the research focus to the international literature on structural inequalities
The author clearly presents the argument of the research
The author clarifies how the research is inspired by and uses the concept of ‘subalternity’.

Thus, the author successfully introduces the literature review, from which point onward it dives into the main concept (‘subalternity’) of the research, and reviews the literature on socio-economic justice and environmental degradation.

While introductions to a literature review section aren’t always required to offer the same level of study context detail as demonstrated here, this introduction serves as a commendable model for orienting the reader within the literature review. It effectively underscores the literature review’s significance within the context of the study being conducted.

Examples 3-5: Effective introductions to literature review chapters

The introduction to a literature review chapter can vary in length, depending largely on the overall length of the literature review chapter itself. For example, a master’s thesis typically features a more concise literature review, thus necessitating a shorter introduction. In contrast, a Ph.D. thesis, with its more extensive literature review, often includes a more detailed introduction.

Numerous universities offer online repositories where you can access theses and dissertations from previous years, serving as valuable sources of reference. Many of these repositories, however, may require you to log in through your university account. Nevertheless, a few open-access repositories are accessible to anyone, such as the one by the University of Manchester . It’s important to note though that copyright restrictions apply to these resources, just as they would with published papers.

Master’s thesis literature review introduction

The first example is “Benchmarking Asymmetrical Heating Models of Spider Pulsar Companions” by P. Sun, a master’s thesis completed at the University of Manchester on January 9, 2024. The author, P. Sun, introduces the literature review chapter very briefly but effectively:

PhD thesis literature review chapter introduction

The second example is Deep Learning on Semi-Structured Data and its Applications to Video-Game AI, Woof, W. (Author). 31 Dec 2020, a PhD thesis completed at the University of Manchester . In Chapter 2, the author offers a comprehensive introduction to the topic in four paragraphs, with the final paragraph serving as an overview of the chapter’s structure:

PhD thesis literature review introduction

The last example is the doctoral thesis Metacognitive strategies and beliefs: Child correlates and early experiences Chan, K. Y. M. (Author). 31 Dec 2020 . The author clearly conducted a systematic literature review, commencing the review section with a discussion of the methodology and approach employed in locating and analyzing the selected records.

Having absorbed all of this information, let’s recap the essential steps and offer a succinct guide on how to proceed with creating your literature review introduction:

Contextualize your review : Begin by clearly identifying the academic context in which your literature review resides and determining the necessary information to include.
Outline your structure : Develop a structured outline for your literature review, highlighting the essential information you plan to incorporate in your introduction.
Literature review process : Conduct a rigorous literature review, reviewing and analyzing relevant sources.
Summarize and abstract : After completing the review, synthesize the findings and abstract key insights, trends, and knowledge gaps from the literature.
Craft the introduction : Write your literature review introduction with meticulous attention to the seamless integration of your review into the larger context of your work. Ensure that your introduction effectively elucidates your rationale for the chosen review topics and the underlying reasons guiding your selection.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

An introductory paragraph that explains what your working topic and thesis is
A forecast of key topics or texts that will appear in the review
Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
Critically Evaluate: Mention the strengths and weaknesses of your sources
Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

Summarize the key findings you have taken from the literature and emphasize their significance
Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
Qualitative versus quantitative research
Empirical versus theoretical scholarship
Divide the research by sociological, historical, or cultural sources
Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

keep track of the search items you use (so that your search can be replicated [10] ),
keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

discussing in your review the approaches, limitations, and conclusions of past reviews,
trying to find a new angle that has not been covered adequately in the previous reviews, and
incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

be thorough,
use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

the major achievements in the reviewed field,
the main areas of debate, and
the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

Before getting started on sourcing and reviewing the background literature for a research project, it is important to understand the role that a literature review plays in the research process, and how it can be helpful later on for placing your own findings in context. Knowing the job that a literature review does means you can be more targeted and systematic in your literature searching. The guidance on this page will explain what you need to know about the purpose of a literature review and how to begin scoping your search.

New discoveries don't materialise out of nowhere; they build upon the findings of previous experiments and investigations. A literature review shows how the investigation you are conducting fits with what has gone before and puts it into context.

If you are doing a thesis, dissertation, or a long report it is likely that you will need to include a literature review. If you are doing a lab write-up or a shorter report, some background reading may be required to give context to your work, but this is usually included as an analysis in the introduction and discussion sections.

A literature review is a select analysis of existing research which is relevant to your topic, showing how it relates to your investigation. It explains and justifies how your investigation may help answer some of the questions or gaps in this area of research.

A literature review is not a straightforward summary of everything you have read on the topic and it is not a chronological description of what was discovered in your field.

A longer literature review may have headings to help group the relevant research into themes or topics. This gives a focus to your analysis, as you can group similar studies together and compare and contrast their approaches, any weaknesses or strengths in their methods, and their findings.

One common way to approach a literature review is to start out broad and then become more specific . Think of it as an inverted triangle:

First briefly explain the broad issues related to your investigation; you don't need to write much about this, just demonstrate that you are aware of the breadth of your subject.
Then narrow your focus to deal with the studies that overlap with your research.
Finally, hone in on any research which is directly related to your specific investigation. Proportionally you spend most time discussing those studies which have most direct relevance to your research.

What research has already been done on this topic?
What are the sub-areas of the topic you need to explore?
What other research (perhaps not directly on the topic) might be relevant to your investigation?
How do these sub-topics and other research overlap with your investigation?

Note down all your initial thoughts on the topic. You can use a spidergram or list to help you identify the areas you want to investigate further. It is important to do this before you start reading so that you don't waste time on unfocussed and irrelevant reading.

It's easy to think that the best way to search for texts is to use the Internet - to 'Google it'. There are useful online tools that you may use, like Google Scholar. However, for most literature reviews you will need to focus on academically authoritative texts like academic books, journals, research reports, government publications. Searching Google will give you thousands of hits, few of them authoritative, and you will waste time sorting through them.

A better idea is to use databases. These are available through the Library in paper and electronic (usually online) forms.

Use journal articles: They normally have the most up-to-date research and you will be expected to refer to them in your literature review. The Library has a guide on finding journal articles.

The Library also has an Academic Liaison Librarian for each subject and guides to finding information in your subject.

You may find review articles that survey developments in your field. These are very useful for identifying relevant sources - but do go back to the original texts and develop your own critical analysis if possible.

Another good way to find sources is to look at the reference lists in articles or books already identified as relevant to your topic. You will be expected to prioritise recent research, but it's also important to acknowledge the standard texts in your field. An easy way to identify these is to check reference lists to see which texts are frequently cited.

Ah, how to start a literature review – those words will be all too familiar to battle-hardened researchers, but to the rest of us, they may be a bit of a mystery.

Are you a student trying to get ahead of the game with your first literature review? Or are you a professional looking to learn more about literature reviews? If so, then this post is for you.

In this article, we’ll discuss how to start a literature review, the types of sources used in literature reviews, and the benefits of writing them. We’ll also outline the steps for preparing and writing your own literature review.

Read on and let the magic begin!

Literature Reviews – The Researcher’s Friend

A literature review is an essential part of any research project. It is a compilation of all the literature and research related to a particular topic. It is used to provide context and background for a research project. Literature reviews are important for two primary reasons. First, they provide a comprehensive and objective review of the existing literature on a topic. Second, they provide support for any conclusions or hypotheses that may be drawn from the research.

Literature reviews are used in many different fields, including business, education, and the sciences. They are used to provide an overview of a topic and to support the conclusions and hypotheses of a research project.

What is a Literature Review?

A literature review is a critical appraisal of existing research on a particular topic . It is a systematic and comprehensive review of all the published work in a particular field. The purpose of a literature review is to provide an overview of the existing research on a topic, to identify gaps in the literature, and to propose new directions for future research.

The literature review is an important part of the research process and should be conducted thoroughly and objectively. It should include a critical analysis of the existing literature, an evaluation of the research methods used, and an assessment of the quality of the evidence.

Types of Literature Review

There are several different types of literature reviews. They include narrative reviews, systematic reviews, meta-analyses, and scoping reviews.

Narrative reviews are the most common type of literature review. They provide an overview of the existing literature on a topic. Narrative reviews typically include an introduction, a review of the literature, and a conclusion.
Systematic reviews are more rigorous and comprehensive than narrative reviews. They involve rigorous and systematic searches of the literature and include a critical appraisal of the evidence. Systematic reviews are typically used in clinical research.
Meta-analyses are reviews that combine the results of multiple studies to evaluate the overall effect of a particular treatment or intervention. Meta-analyses are more rigorous and comprehensive than narrative reviews and systematic reviews.
Scoping reviews are used to identify the range of research on a particular topic. They are typically used to identify gaps in the literature and to propose new directions for future research.

Sourcing Pieces for Your Review

When conducting a literature review, it is important to use a variety of sources. These sources include journal articles, books, conference proceedings, dissertations, and other academic sources. It is also important to use a variety of search strategies to identify the most relevant and up-to-date sources.

Research papers will probably form the bulk of your literature review, and this is where Audemic can help – simply load any papers you want to use into the app, and you can organise them intuitively to make sourcing a breeze.

It is important to note that not all sources are created equal. Some sources may be more reliable than others. When evaluating sources for your literature review, it is important to consider their credibility, relevance, accuracy, and objectivity.

Benefits of Literature Reviews

Literature reviews are an essential part of any research project. They provide an overview of the existing literature on a topic and can be used to identify gaps in the literature, as well as propose new directions for future research. They also provide support for any conclusions or hypotheses that may be drawn from the research.

Literature reviews can also help researchers save time and money. By conducting a thorough and comprehensive review of the existing literature, researchers can avoid redundant research and save time and money.

How to Start a Literature Review

Now that you understand the purpose and benefits of a literature review, it’s time to learn how to start one. The first step in starting a literature review is to identify a topic. Once you have identified a topic, you can start searching for sources.

When searching for sources, it is important to use a variety of search strategies, such as keyword searches, author searches, and database searches. It is also important to use a variety of sources, such as journal articles, books, conference proceedings, and dissertations.

Preparing for Your Literature Review

Once you have identified and located the sources for your literature review, it is time to start preparing. Before you begin writing, it is important to read and analyse each source. This will help you identify the key points of each source and understand how it contributes to the literature on your topic.

It is also important to organise your sources. This can be done by creating a spreadsheet or using a reference management software, such as Mendeley or Zotero. This will help you keep track of your sources and make it easier to cite them in your literature review.

Did somebody say Zotero? Audemic features Zotero integration, so you can not only organise your sources, but also listen to them when you need a change of pace. Nice, eh?

Searching for Sources for Your Review

Now that you have identified a topic and prepared your sources, it’s time to start searching for additional sources. When searching for sources, it is important to use a variety of search strategies. These search strategies include keyword searches, author searches, database searches, and library catalogue searches.

It is also important to use a variety of sources. These sources include journal articles, books, conference proceedings, dissertations, and other academic sources. It is also important to consider the credibility, relevance, accuracy, and objectivity of each source.

Writing and Structuring Your Literature Review

Once you have identified and located the sources for your literature review, it is time to start writing. When writing your literature review, it is important to keep the structure and organisation in mind. Your literature review should include an introduction, a review of the literature, and a conclusion.

When writing your introduction , it is important to provide context for your topic. This should include an explanation of the purpose of the literature review and a description of the research question.
The review of the literature should provide an overview of the existing literature on the topic. It should include a summary of each source and an analysis of the evidence. It should also include an evaluation of the research methods used and an assessment of the quality of the evidence.
Finally, the conclusion should summarise the key points of the literature review and provide recommendations for future research.

Final Thoughts

A literature review is an essential part of any research project, so it pays to master this critical academic skill. And with the guidance in this post, you should be well on your way to knowing how to start a literature review for yourself. By putting it into practice, you can unlock your writing potential and produce a thorough, engaging and comprehensive literature review.

So what are you waiting for? Search for those sources and get started! And why not use Audemic to speed up the review process and boost it into the cosmos!

Keep striving, researchers! ✨

How to Write a Literature Review

Start drafting.

It’s time to start drafting your paper. Follow the structure from your outline and start filling in the missing parts. Get out your notes and remind yourself of the sources you plan to talk about. You don’t have to write your paper from beginning to end in order–you can go to the parts that feel the easiest and start there. Here are some places you can start:

Bullet-Point Draft

With a Bullet-Point draft you take the ideas you’ve been outlining and fill them in with more details but only in bullet-point form. The beauty of bullet points is that they keep you from getting caught up in the language and style and allow you to focus simply on your main points. You can smooth out the sentences and transitions later, but for now, just get your ideas on the page.

Write the Introduction

Another way to get started is to write the Introduction. You already have a thesis statement, so now you can start introducing your topic and its importance, setting up your literature review.

Write a Body Paragraph

Or a third place to start is to jump into writing a body paragraph that synthesizes your sources. Use your notes and outline, and choose one set to talk about in paragraph form.

Don’t think too hard about getting things perfect when you’re drafting–that’s what revision is for. Just focus on getting started. If you get stuck, do some brainstorming activities to get your creative juices flowing. Once you have something written, I suggest seeking feedback to make sure you’re going in the right direction. In fact, I recommend getting as much feedback as possible along the way.

As you create a draft, try to incorporate several sources into each paragraph to be sure that you’re synthesizing and not just summarizing or listing without making connections. Your color-coded notes can help you be sure that you’re synthesizing.

Add Metacommentary

Metacommentary is the key to synthesis. Metacommentary (aka metadiscourse) is a type of commentary that guides your reader and helps them interpret the sources and evidence you’re presenting. Think of it as really powerful transitions.

Transition words act like signposts–they guide your reader through your points. They can also glue your ideas together so they feel more cohesive. Beware that transitions can definitely be overdone, but most students in general could use more transitions in their papers rather than fewer.

You might think you can just stop at transition words, but metacommentary is much more than just sprinkling some “therefores” and “howevers” throughout your paper–metacommentary actually takes your synthesis to the next level. What do you comment on? You can either interpret why a source is important, highlight its significance, or connect it with other sources. This is your chance to point out the answers to the four questions you looked for in your note-taking:

What do researchers agree and disagree about?

How are researchers narrowing or changing their focus to create new information?

What are each study’s limitations and strengths?

What’s the next step in research—what should be studied in the future? (The research gap)

You can think of metacommentary as a sandwich with your name on it. If my student’s name were Alisa, here’s what and Alisa sandwich would look like:

ALISA-SOURCE-ALISA

First, Alisa starts with a claim about what’s happening in the field or about a particular subsection or focus of the field. This could serve as a topic sentence for a paragraph, for example.

Second, she sets up the source with guiding language like transitions and references to her past points or sources.

Third, she writes about the source itself and summarizes pertinent information.

Lastly, Alisa comments on the source and/or connects it to her main point or to next source.

This type of sandwich can occur several times in a paragraph as you synthesize your sources. Here’s a sample paragraph from Chris, a Public Health student, who wrote a paper called “The Causes of a Behavioral Pandemic: Screen-time Addiction and Consequent Depression Among Adolescents.” I’ve bolded the metacommentary Chris included to guide his readers and to connect his points.

Even though there have been far fewer studies on adolescents than adults , adolescent studies have consistently shown that those who are more physically active experience less depressive and associated symptoms, as well as a greater overall state of well-being (Kremer, 2014). These studies have also shown that low levels of vigorous exercise in youth can independently cause depressive symptoms. One longitudinal study revealed that over 30% of children who participate in high levels of screen-time use experience moderate to high levels of depressive symptoms (Kremer, 2014). Additionally, another study of children in the United States demonstrated that those who participated on a sports team were less likely to exceed recommended screen-time limits established by the US Department of Health. This study also demonstrated that as the number of total physical activity sessions increased among youth, both during free time and at organized events, children were less likely to exceed recommended screen-time limits (Carlson, 2010). In this study, children who were more physically active consistently showed lower rates of depression and other emotional disorders. Therefore, evidence across multiple studies suggests that participating in screen-time activity may not be the direct cause of depressive symptoms, but rather the sedentary lifestyle and lack physical activity it causes among youth. With this recent evidence, experts are beginning to search for ways to replace screen-time participation of adolescents with physical activities.

Note how the last few sentences of this paragraph consist entirely of metacommentary–points that connect to the bigger picture of Chris’s literature review. Also notice how Chris uses transition words and phrases to glue his points together so it doesn’t come out of the blue when he brings up a new study. Also, Chris discusses more than one study in this paragraph, demonstrating his ability to synthesize and not just summarize. Without the metacommentary, it would be much harder to see the connections between the studies and how they fit into the bigger picture. Finally, Chris indicates the implications of these studies and points to what researchers are doing next . This has a duel purpose of reminding readers why this topic is important as well as indicating where he will go in his next paragraph (about physical activities). Metacommentary is powerful!

Metacommentary takes practice, but you can do it! And it will not only make your points stronger, it will make it easier for your audience to read and understand–which should always be your goal.

If You Get Stuck

Literature reviews can be hard. If you get stuck, I have a little trick I tell my students. For your first draft, try starting every sentence with “Researchers . . .” I know this seems formulaic, but if you can keep your focus on what particular researchers did or what they agree or disagree on, you’ll avoid the most common pitfalls of literature reviews: sounding like a typical argumentative research paper. If your focus is always on what researchers are doing or what they’ve found, then at the very least you’ll stay in the realm of the literature review genre. Later you can go back through and change up your sentence structure, but I’ve found that this is an easy way for students to get through a first draft.

The Real Last Step: Revise (and Revise and Revise)

Fantastic BYU Family Science professor Julie Haupt offers the following suggestions for doing four purposeful revisions–two global and two local.

GLOBAL REVISION–The Forest

Level 1: structural review (global).

Purpose: The structural review examines the document as a whole to see if all requirements are met and the document’s organization is sound.

Meet Assignment Requirements. Ask yourself if your paper meets all the requirements of the assignment? Look at your structure and make sure you have all necessary sections such as the following:

Introduction (with Thesis Statement and/or Organizing Statement)

Body with Headings

Conclusion/Discussion

Include a Thesis and an Organizing Statement. Does the current version of the thesis statement match the tone, scope, and organization of the body text? Does an organizing statement after the thesis introduce the major topics and the order they will appear in the body (e.g., “This review will first discuss . . . then . . . and finally . . .)

Use Headings. Is the body text subdivided in a logical way with evidence-based information located in appropriate sections? Are the major sections roughly symmetrical (in terms of length)? Are the headings brief, yet descriptive? If subheadings are used, does the major section contain at least two? Are all levels of headings separated by text?

Level 2 (Global): Paragraph/Logic Review

Purpose: The Paragraph/Logic Review is designed to review each paragraph for cohesion and compliance to the CEC (Claim/Evidence/Commentary) format.

Sequence Paragraphs Effectively. When reading only the first sentence of each paragraph, does the logical pattern of the paper emerge? Do the claims made in these topic sentences coordinate well with the thesis of the paper?

Check Topic Sentences and Cohesion. Does the topic sentence or claim provide an effective overview of the information that is located in the paragraph? Is the claim supported by several points of synthesized evidence, rather than a single study? Does each paragraph seem well directed and cohesive? Do the sentences build one upon another within the paragraph in a logical way?

Evaluate Paragraph Length. Are any paragraphs too long (longer than approximately ½ page)? Are any paragraphs too short (approximately three sentences or less)? Do paragraphs transition well from one to the next and use transitional words to connect ideas?

LOCAL REVISION–The Tree

Level 3 (local): apa formatting review.

Purpose: The APA Formatting Review is designed to make sure all APA conventions are explicitly followed to help the paper reflect a high level of professionalism.

Check Document Formatting. Do the body text and reference page appear in the correct page formatting as required? (Use the APA Manual if you have questions.)

Examine the Reference List Closely. Are all references in the reference list ordered alphabetically? Is the reference list double spaced entirely (with no extra gaps between paragraphs)? Are all references (e.g., journal articles, internet resources, or books) listed in the correct format? Is every reference on the reference list cited at least once in the body and does each in-text citation have a corresponding reference in the reference list?

Make a Final Check of the In-Text Citations. Is all information properly cited with an in-text citation when needed? Do all in-text citations include the year next to the author(s)? When more than one citation is listed within parentheses are they separated by semi-colons and ordered alphabetically by first author’s last name? If included in parentheses, do studies with multiple authors use ampersands (“&” rather than the word “and”) before listing the last author?

Level 4 (Local): Finishing Review

Purpose: The Finishing Review is an opportunity to look closely at sentence construction, language, hedging , and grammar/punctuation.

Review Phrasing with a Read-Aloud Session. Since having to read a sentence twice to get its meaning or “tripping over” phrasing can be an indication of awkward construction, are all sentences easily read aloud? Are any sentences so long that they have become difficult to comprehend, but could be split without changing the meaning?

Use Non-Biased, Non-Absolute Language. Do all references to people comply with the “people first” designation and avoid inappropriate uses of terms for various groups? Are the findings and summary statements in the review properly “ Hedged ”?

Check Punctuation and Grammar. Are all commas, semicolons, colons, hyphens, and other punctuation used correctly throughout the document (including the reference page)? Are common grammar mistakes, such as parallelism, subject-verb agreement, incorrect misuse of pronouns, and other grammatical issues corrected?

Literature Reviews

What this handout is about.

This handout will explain what literature reviews are and offer insights into the form and construction of literature reviews in the humanities, social sciences, and sciences.

Introduction

OK. You’ve got to write a literature review. You dust off a novel and a book of poetry, settle down in your chair, and get ready to issue a “thumbs up” or “thumbs down” as you leaf through the pages. “Literature review” done. Right?

Wrong! The “literature” of a literature review refers to any collection of materials on a topic, not necessarily the great literary texts of the world. “Literature” could be anything from a set of government pamphlets on British colonial methods in Africa to scholarly articles on the treatment of a torn ACL. And a review does not necessarily mean that your reader wants you to give your personal opinion on whether or not you liked these sources.

What is a literature review, then?

A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period.

A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information. It might give a new interpretation of old material or combine new with old interpretations. Or it might trace the intellectual progression of the field, including major debates. And depending on the situation, the literature review may evaluate the sources and advise the reader on the most pertinent or relevant.

But how is a literature review different from an academic research paper?

The main focus of an academic research paper is to develop a new argument, and a research paper is likely to contain a literature review as one of its parts. In a research paper, you use the literature as a foundation and as support for a new insight that you contribute. The focus of a literature review, however, is to summarize and synthesize the arguments and ideas of others without adding new contributions.

Why do we write literature reviews?

Literature reviews provide you with a handy guide to a particular topic. If you have limited time to conduct research, literature reviews can give you an overview or act as a stepping stone. For professionals, they are useful reports that keep them up to date with what is current in the field. For scholars, the depth and breadth of the literature review emphasizes the credibility of the writer in his or her field. Literature reviews also provide a solid background for a research paper’s investigation. Comprehensive knowledge of the literature of the field is essential to most research papers.

Who writes these things, anyway?

Literature reviews are written occasionally in the humanities, but mostly in the sciences and social sciences; in experiment and lab reports, they constitute a section of the paper. Sometimes a literature review is written as a paper in itself.

Let’s get to it! What should I do before writing the literature review?

If your assignment is not very specific, seek clarification from your instructor:

Roughly how many sources should you include?
What types of sources (books, journal articles, websites)?
Should you summarize, synthesize, or critique your sources by discussing a common theme or issue?
Should you evaluate your sources?
Should you provide subheadings and other background information, such as definitions and/or a history?

Find models

Look for other literature reviews in your area of interest or in the discipline and read them to get a sense of the types of themes you might want to look for in your own research or ways to organize your final review. You can simply put the word “review” in your search engine along with your other topic terms to find articles of this type on the Internet or in an electronic database. The bibliography or reference section of sources you’ve already read are also excellent entry points into your own research.

Narrow your topic

There are hundreds or even thousands of articles and books on most areas of study. The narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good survey of the material. Your instructor will probably not expect you to read everything that’s out there on the topic, but you’ll make your job easier if you first limit your scope.

Keep in mind that UNC Libraries have research guides and to databases relevant to many fields of study. You can reach out to the subject librarian for a consultation: https://library.unc.edu/support/consultations/ .

And don’t forget to tap into your professor’s (or other professors’) knowledge in the field. Ask your professor questions such as: “If you had to read only one book from the 90’s on topic X, what would it be?” Questions such as this help you to find and determine quickly the most seminal pieces in the field.

Consider whether your sources are current

Some disciplines require that you use information that is as current as possible. In the sciences, for instance, treatments for medical problems are constantly changing according to the latest studies. Information even two years old could be obsolete. However, if you are writing a review in the humanities, history, or social sciences, a survey of the history of the literature may be what is needed, because what is important is how perspectives have changed through the years or within a certain time period. Try sorting through some other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to consider what is currently of interest to scholars in this field and what is not.

Strategies for writing the literature review

Find a focus.

A literature review, like a term paper, is usually organized around ideas, not the sources themselves as an annotated bibliography would be organized. This means that you will not just simply list your sources and go into detail about each one of them, one at a time. No. As you read widely but selectively in your topic area, consider instead what themes or issues connect your sources together. Do they present one or different solutions? Is there an aspect of the field that is missing? How well do they present the material and do they portray it according to an appropriate theory? Do they reveal a trend in the field? A raging debate? Pick one of these themes to focus the organization of your review.

Convey it to your reader

A literature review may not have a traditional thesis statement (one that makes an argument), but you do need to tell readers what to expect. Try writing a simple statement that lets the reader know what is your main organizing principle. Here are a couple of examples:

The current trend in treatment for congestive heart failure combines surgery and medicine. More and more cultural studies scholars are accepting popular media as a subject worthy of academic consideration.

Consider organization

You’ve got a focus, and you’ve stated it clearly and directly. Now what is the most effective way of presenting the information? What are the most important topics, subtopics, etc., that your review needs to include? And in what order should you present them? Develop an organization for your review at both a global and local level:

First, cover the basic categories

Just like most academic papers, literature reviews also must contain at least three basic elements: an introduction or background information section; the body of the review containing the discussion of sources; and, finally, a conclusion and/or recommendations section to end the paper. The following provides a brief description of the content of each:

Introduction: Gives a quick idea of the topic of the literature review, such as the central theme or organizational pattern.
Body: Contains your discussion of sources and is organized either chronologically, thematically, or methodologically (see below for more information on each).
Conclusions/Recommendations: Discuss what you have drawn from reviewing literature so far. Where might the discussion proceed?

Organizing the body

Once you have the basic categories in place, then you must consider how you will present the sources themselves within the body of your paper. Create an organizational method to focus this section even further.

To help you come up with an overall organizational framework for your review, consider the following scenario:

You’ve decided to focus your literature review on materials dealing with sperm whales. This is because you’ve just finished reading Moby Dick, and you wonder if that whale’s portrayal is really real. You start with some articles about the physiology of sperm whales in biology journals written in the 1980’s. But these articles refer to some British biological studies performed on whales in the early 18th century. So you check those out. Then you look up a book written in 1968 with information on how sperm whales have been portrayed in other forms of art, such as in Alaskan poetry, in French painting, or on whale bone, as the whale hunters in the late 19th century used to do. This makes you wonder about American whaling methods during the time portrayed in Moby Dick, so you find some academic articles published in the last five years on how accurately Herman Melville portrayed the whaling scene in his novel.

Now consider some typical ways of organizing the sources into a review:

Chronological: If your review follows the chronological method, you could write about the materials above according to when they were published. For instance, first you would talk about the British biological studies of the 18th century, then about Moby Dick, published in 1851, then the book on sperm whales in other art (1968), and finally the biology articles (1980s) and the recent articles on American whaling of the 19th century. But there is relatively no continuity among subjects here. And notice that even though the sources on sperm whales in other art and on American whaling are written recently, they are about other subjects/objects that were created much earlier. Thus, the review loses its chronological focus.
By publication: Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on biological studies of sperm whales if the progression revealed a change in dissection practices of the researchers who wrote and/or conducted the studies.
By trend: A better way to organize the above sources chronologically is to examine the sources under another trend, such as the history of whaling. Then your review would have subsections according to eras within this period. For instance, the review might examine whaling from pre-1600-1699, 1700-1799, and 1800-1899. Under this method, you would combine the recent studies on American whaling in the 19th century with Moby Dick itself in the 1800-1899 category, even though the authors wrote a century apart.
Thematic: Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For instance, the sperm whale review could focus on the development of the harpoon for whale hunting. While the study focuses on one topic, harpoon technology, it will still be organized chronologically. The only difference here between a “chronological” and a “thematic” approach is what is emphasized the most: the development of the harpoon or the harpoon technology.But more authentic thematic reviews tend to break away from chronological order. For instance, a thematic review of material on sperm whales might examine how they are portrayed as “evil” in cultural documents. The subsections might include how they are personified, how their proportions are exaggerated, and their behaviors misunderstood. A review organized in this manner would shift between time periods within each section according to the point made.
Methodological: A methodological approach differs from the two above in that the focusing factor usually does not have to do with the content of the material. Instead, it focuses on the “methods” of the researcher or writer. For the sperm whale project, one methodological approach would be to look at cultural differences between the portrayal of whales in American, British, and French art work. Or the review might focus on the economic impact of whaling on a community. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed. Once you’ve decided on the organizational method for the body of the review, the sections you need to include in the paper should be easy to figure out. They should arise out of your organizational strategy. In other words, a chronological review would have subsections for each vital time period. A thematic review would have subtopics based upon factors that relate to the theme or issue.

Sometimes, though, you might need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. Put in only what is necessary. Here are a few other sections you might want to consider:

Current Situation: Information necessary to understand the topic or focus of the literature review.
History: The chronological progression of the field, the literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
Methods and/or Standards: The criteria you used to select the sources in your literature review or the way in which you present your information. For instance, you might explain that your review includes only peer-reviewed articles and journals.

Questions for Further Research: What questions about the field has the review sparked? How will you further your research as a result of the review?

Begin composing

Once you’ve settled on a general pattern of organization, you’re ready to write each section. There are a few guidelines you should follow during the writing stage as well. Here is a sample paragraph from a literature review about sexism and language to illuminate the following discussion:

However, other studies have shown that even gender-neutral antecedents are more likely to produce masculine images than feminine ones (Gastil, 1990). Hamilton (1988) asked students to complete sentences that required them to fill in pronouns that agreed with gender-neutral antecedents such as “writer,” “pedestrian,” and “persons.” The students were asked to describe any image they had when writing the sentence. Hamilton found that people imagined 3.3 men to each woman in the masculine “generic” condition and 1.5 men per woman in the unbiased condition. Thus, while ambient sexism accounted for some of the masculine bias, sexist language amplified the effect. (Source: Erika Falk and Jordan Mills, “Why Sexist Language Affects Persuasion: The Role of Homophily, Intended Audience, and Offense,” Women and Language19:2).

Use evidence

In the example above, the writers refer to several other sources when making their point. A literature review in this sense is just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence to show that what you are saying is valid.

Be selective

Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the review’s focus, whether it is thematic, methodological, or chronological.

Use quotes sparingly

Falk and Mills do not use any direct quotes. That is because the survey nature of the literature review does not allow for in-depth discussion or detailed quotes from the text. Some short quotes here and there are okay, though, if you want to emphasize a point, or if what the author said just cannot be rewritten in your own words. Notice that Falk and Mills do quote certain terms that were coined by the author, not common knowledge, or taken directly from the study. But if you find yourself wanting to put in more quotes, check with your instructor.

Summarize and synthesize

Remember to summarize and synthesize your sources within each paragraph as well as throughout the review. The authors here recapitulate important features of Hamilton’s study, but then synthesize it by rephrasing the study’s significance and relating it to their own work.

Keep your own voice

While the literature review presents others’ ideas, your voice (the writer’s) should remain front and center. Notice that Falk and Mills weave references to other sources into their own text, but they still maintain their own voice by starting and ending the paragraph with their own ideas and their own words. The sources support what Falk and Mills are saying.

Use caution when paraphrasing

When paraphrasing a source that is not your own, be sure to represent the author’s information or opinions accurately and in your own words. In the preceding example, Falk and Mills either directly refer in the text to the author of their source, such as Hamilton, or they provide ample notation in the text when the ideas they are mentioning are not their own, for example, Gastil’s. For more information, please see our handout on plagiarism .

Revise, revise, revise

Draft in hand? Now you’re ready to revise. Spending a lot of time revising is a wise idea, because your main objective is to present the material, not the argument. So check over your review again to make sure it follows the assignment and/or your outline. Then, just as you would for most other academic forms of writing, rewrite or rework the language of your review so that you’ve presented your information in the most concise manner possible. Be sure to use terminology familiar to your audience; get rid of unnecessary jargon or slang. Finally, double check that you’ve documented your sources and formatted the review appropriately for your discipline. For tips on the revising and editing process, see our handout on revising drafts .

How To Structure Your Literature Review

3 options to help structure your chapter.

By: Amy Rommelspacher (PhD) | Reviewer: Dr Eunice Rautenbach | November 2020 (Updated May 2023)

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

Demonstrate your knowledge of the research topic
Identify the gaps in the literature and show how your research links to these
Provide the foundation for your conceptual framework (if you have one)
Inform your own methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter.

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess.

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write.

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an introduction , a body and a conclusion .

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Example of literature review outline structure

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you will and won’t be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies).

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way.

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking) three options for organising your literature review.

The body section of your literature review is the where you'll present, analyse, evaluate and synthesise the existing research.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

Adopting the chronological structure allows you to discuss the developments and debates in the field as they emerged over time.

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

What is the earliest literature published relating to this topic?
How has the field changed over time? Why?
What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

The thematic structure allows you to organise your literature by theme or category – e.g. by independent variables.

Here are some questions to ask yourself when structuring your literature review by themes:

Are there any patterns that have come to light in the literature?
What are the central themes and categories used by the researchers?
Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question how existing research has been conducted, as opposed to what the conclusions and/or findings the research were.

The methodological structure allows you to organise your chapter by the analysis method used - e.g. qual, quant or mixed.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

In the conclusion section, you’ll need to present the key findings of your literature review and highlight the gaps that exist in the literature. Based on this, you'll need to make it clear what your study will add to the literature.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve discussed how to structure your literature review for maximum impact. Here’s a quick recap of what you need to keep in mind when deciding on your literature review structure:

Just like other chapters, your literature review needs a clear introduction , body and conclusion .
The introduction section should provide an overview of what you will discuss in your literature review.
The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
The conclusion section should draw together the key findings of your literature review and link them to your research questions.

Great work. This is exactly what I was looking for and helps a lot together with your previous post on literature review. One last thing is missing: a link to a great literature chapter of an journal article (maybe with comments of the different sections in this review chapter). Do you know any great literature review chapters?

I agree with you Marin… A great piece

I agree with Marin. This would be quite helpful if you annotate a nicely structured literature from previously published research articles.

Awesome article for my research.

I thank you immensely for this wonderful guide

It is indeed thought and supportive work for the futurist researcher and students

Very educative and good time to get guide. Thank you

Great work, very insightful. Thank you.

Thanks for this wonderful presentation. My question is that do I put all the variables into a single conceptual framework or each hypothesis will have it own conceptual framework?

Thank you very much, very helpful

This is very educative and precise . Thank you very much for dropping this kind of write up .

Pheeww, so damn helpful, thank you for this informative piece.

I’m doing a research project topic ; stool analysis for parasitic worm (enteric) worm, how do I structure it, thanks.

comprehensive explanation. Help us by pasting the URL of some good “literature review” for better understanding.

great piece. thanks for the awesome explanation. it is really worth sharing. I have a little question, if anyone can help me out, which of the options in the body of literature can be best fit if you are writing an architectural thesis that deals with design?

I am doing a research on nanofluids how can l structure it?

Beautifully clear.nThank you!

Lucid! Thankyou!

Brilliant work, well understood, many thanks

I like how this was so clear with simple language 😊😊 thank you so much 😊 for these information 😊

Insightful. I was struggling to come up with a sensible literature review but this has been really helpful. Thank you!

You have given thought-provoking information about the review of the literature.

Thank you. It has made my own research better and to impart your work to students I teach

I learnt a lot from this teaching. It’s a great piece.

I am doing research on EFL teacher motivation for his/her job. How Can I structure it? Is there any detailed template, additional to this?

You are so cool! I do not think I’ve read through something like this before. So nice to find somebody with some genuine thoughts on this issue. Seriously.. thank you for starting this up. This site is one thing that is required on the internet, someone with a little originality!

I’m asked to do conceptual, theoretical and empirical literature, and i just don’t know how to structure it

revising your literature review

Note: Because this chapter involves the steps for writing your Literature Review, the discussion questions in each section will be more involved than in other chapters, so give yourself extra time. But never fear! They will all lead to writing a better paper.

12.1 Draft and Synthesize

First, I want you to watch this 10-minute video because it both reviews what we talked about in the last chapter and provides great ways to get started on the actual writing of your paper. Here are some highlights to pay attention to:

questions to ask as you take or review your notes that will guide your writing

suggestions for how to organize your notes. (Or actually, I should spell it "organise" with an "s" since the video comes from Australia.)

ways to add interpretation to what you say about your sources

language to use to comment on the studies you're summarizing and synthesizing

examples of literature review synthesis

Video Review

What three strategies or elements from the video do you plan to incorporate into your own Literature Review?

Start Drafting

Now it's time to start drafting your paper. Follow the structure from your outline and start filling in the missing parts. Get out your notes and remind yourself of the sources you plan to talk about. You don't have to write your paper from beginning to end in order—you can go to the parts that feel the easiest and start there. Here are some places you can start:

Bullet-Point Draft

Writing your Bullet Points should be as fast as this Bullet Train. Photo by Fikri Rasyid on Unsplash

I often have my students start with a Bullet-Point draft that takes the ideas they've been outlining and fills them in with more details but only in bullet-point form. The beauty of bullet points is that they keep you from getting caught up in the language and style and allow you to focus simply on your main points. You can smooth out the sentences and transitions later, but for now, just get your ideas on the page.

Write the Introduction

Another way to get started is to just write the Introduction. You already have a thesis statement that can go at the end, so now you can start introducing your topic and its importance, setting up your Literature Review. See below for more specific help with Introductions.

Write a Body Paragraph

Or a third place to start is to jump into writing a body paragraph that synthesizes your sources—the way you did in that synthesis activity earlier. Take your notes and choose one set to talk about in paragraph form.

Don't think too hard about getting things perfect when you're drafting—that's what revision is for. Just focus on getting started and filling in some of the missing pieces. If you get stuck, do some brainstorming activities to get your creative juices flowing. Once you have something written, I suggest seeking feedback to make sure you're going in the right direction. In fact, I recommend getting as much feedback as possible along the way.

Start Writing

Now it's your turn to choose somewhere to start writing—choose either a bullet-point draft, the introduction, a body paragraph or something else. Then write the equivalent of at least one paragraph.

How to Write Each Section

Once you know what your main points will be, you're ready to introduce your ideas. As in any paper, you can't just jump right into your thesis statement and points; you need to set the stage first. Here are the elements of a good introduction to a literature review:

A good introduction

introduces the topic and indicates its importance (impact on individuals)
gives a context for the research question
defines key terms, concepts, and/or theories
explains what search methods were used and how many and what types of sources were reviewed (this is sometimes optional)
suggests the organization of the rest of the paper

Remember in some style guides like the APA Manual , you don't need to title your Introduction "Introduction"—you simply center the title of your paper at the top of your page (bolded and in title capitalization format) and then jump right into your first paragraph.

Tip: You don't always know where you're going when you start a paper, so just get a good draft of an introduction down. Then when you finish writing a first draft of your paper, read your conclusion and consider using some of it in your introduction instead. I often tell my students that conclusions make good introductions because you finally know exactly where you went in your paper. Either way, you'll want to revisit your introduction once your paper's done so you can adjust it to better match where your paper went.

Get a start on your introduction by writing an opening sentence that introduces your topic and/or indicates its importance. Then you can use that to jump start the rest of your introduction.

The body of your paper is where you can develop your points and use your newfound synthesis skills. Remember the synthesis activity with the videos you did in the last chapter? As you create a draft, you can start composing paragraphs using your awesome notes just like you practiced with those videos. Try to incorporate several sources into each paragraph to be sure that you're synthesizing and not just summarizing or listing without making connections. Your color-coded notes can help you be sure that each paragraph contains multiple sources.

In the body of your paper, you should

synthesize previous studies to inform the reader of the state of research

“identify relations, contradictions, gaps, and inconsistencies in the literature” ( APA Manual , p. 8)

group your points into major headings and subheadings (You choose the arrangement based on what you’ve found: similar concepts or theories, similar methods, chronological development, controversies, etc.)

support all points with sound reasoning or evidence drawn from sources and in which all borrowed information is documented

summarize sources most of the time, paraphrase sometimes, and use quotations very sparingly—only when specific wording is poignant or can’t be said in any other way.

One way to talk about your sources is known as the CEC Method: Claim-Evidence-Commentary.

Claim + Evidence + Commentary

Just like any paragraph, you should start with a Topic sentence that acts as a mini-Thesis statement or a general claim about your topic. Then you need to give evidence to support that claim. In a literature review, your evidence comes in the form of studies that have been done—all those brilliant notes you've been taking. This is where you can synthesize your sources and show that they are related under the umbrella of a topic. However, just listing or summarizing sources does not make the connection between them and your topic sentence clear. This is where commentary comes in. Your job is also to comment on and interpret the significance of your "evidence" so your audience can understand the connections between them. In synthesis, your language is the key.

In the next chapter, we'll talk more about how to do this, especially how to incorporate metacommentary into your paragraphs.

Add Metacommentary

Metacommentary is the key to synthesis. metacommentary (aka metadiscourse) is a type of commentary that guides your reader and helps them interpret the sources and evidence you're presenting. Think of it as really powerful transitions. First, let's remind ourselves what transitions are. Transition words act like signposts—they guide your reader through your points. They can also glue your ideas together so they feel more cohesive. Beware that transitions can definitely be overdone, but I'd say most students in general could use more transitions in their papers rather than fewer.

Here's an awesome list of transition words (also linked in the frame below) that are grouped by category from the famous Purdue OWL (Online Writing Lab—scroll down to see the list). You can also download a great handout from the University of Maryland here .

I always suggest that my students keep a categorized transition list like this handy as they write so that when they know they want to connect ideas in a certain way (e.g. to show contrast), you can easily find a good list of options (e.g. in contrast, conversely, etc.). Not only will transitions help your ideas feel more connected, they will also smooth out your writing style like butter.

You might think you can just stop at transition words, but metacommentary is much more than just sprinkling some "therefores" and "howevers" throughout your paper—metacommentary actually takes your synthesis to the next level. Remember the Claim-Evidence-Commentary pattern I've mentioned? The commentary part of that sandwich is where you should focus right now. What do you comment on? You can either highlight why a source is important or connect it with other sources. This is your chance to point out the answers to the four questions you looked for in your note-taking:

What do researchers agree and disagree about?

How are researchers narrowing or changing their focus to create new information?

What are each study’s limitations and strengths?

What’s the next step in research—what should be studied in the future? (The research gap)

You can think of metacommentary as a sandwich with your name on it. If my student's name were Alisa, here's what an "Alisa sandwich" would look like:

ALISA—SOURCE—ALISA

First, Alisa starts with a claim about what's happening in the field or about a particular subsection or focus of the field. This could serve as a topic sentence for a paragraph, for example.

Second, she sets up the source with guiding language like transitions and references to her past points or sources.

Third, she talks about the source itself and summarizes pertinent information.

Lastly, Alisa comments on the source and/or connects it to her main point or to next source.

This metacommentary is a lot like the interpretation mentioned in the video at the beginning of this chapter. This type of "sandwich" can occur several times in a paragraph as you synthesize your sources. Here's a sample paragraph from Chris, a Public Health student, (check this) who wrote a paper called "The Causes of a Behavioral Pandemic: Screen-time Addiction and Consequent Depression Among Adolescents." I've bolded the metacommentary Chris had added to guide his readers and to connect his points together.

Even though there have been far fewer studies on adolescents than adults , adolescent studies have consistently shown that those who are more physically active experience less depressive and associated symptoms, as well as a greater overall state of well-being (Kremer 2014). These studies have also shown that low levels of vigorous exercise in youth can independently cause depressive symptoms. One longitudinal study revealed that over 30% of children who participate in high levels of screen-time use experience moderate to high levels of depressive symptoms (Kremer 2014). Additionally, another study of children in the United States demonstrated that those who participated on a sports team were less likely to exceed recommended screen-time limits established by the US Department of Health. This study also demonstrated that as the number of total physical activity sessions increased among youth, both during free time and at organized events, children were less likely to exceed recommended screen-time limits (Carlson 2010). In this study, children who were more physically active consistently showed lower rates of depression and other emotional disorders. Therefore, evidence across multiple studies suggests that participating in screen-time activity may not be the direct cause of depressive symptoms, but rather the sedentary lifestyle and lack physical activity it causes among youth. With this recent evidence, experts are beginning to search for ways to replace screen-time participation of adolescents with physical activities.

If You Get Stuck

Literature reviews can be hard. If you get stuck, I have a little trick I tell my students. For your first draft, try starting every sentence with "Researchers . . ." I know this seems formulaic, but if you can keep your focus on what particular researchers did or what they agree or disagree on, you'll avoid the most common pitfalls of literature reviews: sounding like a typical argumentative research paper. If your focus is always on what researchers are doing or what they've found, then at the very least you'll stay in the realm of the literature review genre. Later you can go back through and change up your sentence structure, but I've found that this is an easy way for students to get through a first draft.

A Quick Word on Verb Tense

Verb Tenses to Use in Literature Reviews

Discussion/Conclusion

Your last section will either be called discussion or conclusion (or will possibly not have a heading depending on your teacher's preferences or the style guide you're following). In an effective Discussion (aka Conclusion) section you should

do more than sum up what you have said (though you should do that as well)

explain where there are gaps and limitations in the previous research done

indicate recommendations for future research based on those gaps

At the end of this section,

restate your position (thesis statement)

show the implications of your findings

You must also include a list of your References (also known as a Bibliography or Works Cited page depending on the documentation style) showing all the sources you referred to in your paper. Your references page must be in alphabetical order and formatted according to your chosen style guide (see Chapter 9: Talking About Sources ).

Other Elements

Your teacher might require you to include these other elements in your Literature Review paper. Be sure to follow the format from your style guide .

I've waited until now to talk about titles because it's wise to wait until you have a good draft before you choose a title. Why? Because you often don't know exactly where your paper will go until you've written it out. Your title is your readers' first entry into your paper, so you want it to be interesting and also reflect what's inside. Your title should also include as much information as possible while remaining appropriately short and sweet. For example, the APA Manual recommends not using extraneous words but sticking to the main point of your paper. My student Justin's title follows this model:

Implications of Chinese Involvement on Africa's Economy

He basically summarizes his main point in one succinct statement—the ultimate summary. APA would be proud.

360px-Someones_Mullet_from_their_Family_Photos_(39958323871).jpg

However, depending on your sub-field in the Social Sciences, many scholars like to do what I call a "reverse mullet." As you might know, the rad '80s mullet haircut that's short on top and long in the back has been described as

The Mullet: Business in the front, party in the back

A mullet starts with the serious and ends with the fun. But academic titles often do the reverse: they have an interesting introductory phrase, then a colon, and then the standard, more serious title. That's why I call them the

The Reverse Mullet: Party in the front, Business in back

A reverse mullet title gets the reader's attention before adding the serious explanation. For example, one of my students named Katelyn wrote her Literature Review on how much high school students' perception of their teachers was influenced by their teachers' apparel. Her title included a Reverse Mullet structure:

Keeping it Class-y: How Formality of Teacher Apparel Affects Student Perceptions of the Teacher in the Classroom

Your Name (centered)
Your Teacher's Name (centered on the next line)
A Page Number (in the top right corner that's continued throughout the paper)
Optional: the Name of the School or Department
Optional: the Name/Number of Your Course (e.g., English 315)
Optional: the Date

You should save writing your abstract until after you've completed your paper because it's a summary of the main points of your paper. You can try writing a preliminary abstract now as a type of outline, but you run the risk of finding out that once you're done with your paper, you actually went in some different directions. My advice is to hold off and wait to write the abstract until the end. You can create a page after the title page where your abstract will go, but to emphasize that you should write this last, we'll wait to cover the details of writing an an abstract until the next section.

If you have tables or figures ( or formulas or other data) that are too big to be added inside the text of your paper, you can put them at the end. If you only have one Appendix , you can call it just that. But if you have more than one, call them Appendix A, Appendix B, etc. and refer to them as such in the text of your paper.

Tables and Figures

One more element that could be helpful to your paper is to include tables and/or figures. You're probably familiar with Tables (you know, the boxes with lots of horizontal and vertical cells). A Figure is any type of image, graph, or chart besides a table. You can use tables or figures from your sources as long as you cite them properly. You can also create your own table or figure either from existing data or to explain a concept. See Chapter 6: Design for the details of how to create, use, or format tables and figures. Just remember to check your style guide; for example, in APA Format, you need to title and number your tables and figures separately.

I hope you feel like you have a better sense of the structure for your own Literature Review paper. In the next chapter, we'll talk about how to draft and revise your paper.

12.2 Write an Abstract

4k-wallpaper-abstract-abstract-expressionism-abstract-painting-acrylic-paint-art-1563849-pxhere.com.jpg

Not that kind of abstract! As great as abstract art is, what you need now is the abstract of your paper. (Note: some teacher's won't require an abstract, so you can skip this section in that case.) Why do you think we've saved the abstract for last even though it's the first thing your audience will read (after your title)? You guessed it: it's because the abstract is a summary of everything you've talked about in your paper, so if you haven't written your paper yet, it's pretty hard to summarize it.

A lot of students think that the abstract is a preview of your paper that simply invites the reader to learn more. But that's not the purpose of the abstract, that's the purpose of the Introduction . If your paper were a movie, your abstract would not be the movie trailer. A movie trailer is an invitation to see more without giving away too much; that's the point of your Introduction . Instead, your abstract would be the movie plot synopsis. It would have a big SPOILER ALERT sign in front of it because in it you want to give away all the punchlines from your paper. In fact, the more you include your most important points or findings, the better. Because readers might only ever read your abstract, you want the most important information there. Then just like you did in your own database searching, they will decide based on the abstract whether they should open your paper and read more details. Your job is to make sure they have the best information to do that.

An abstract has a few main parts that mirror the parts of your paper but in miniature. First, in 1-2 sentences, you should introduce the topic, its importance, and the problem or question you tried to answer. Then you should succinctly explain your methods (database searching) and the scope of your project. The last and largest part should consist of your main findings such as the main areas of inquiry where researchers are congregating. You should include the major strengths and limitations (gaps) you found in your review. Finally, you should explain any implications of your study and suggest where future research should go. See? A miniature paper. It should be so miniature, that the APA Manual says an abstract should not exceed 250 words. At the end, you can also list a few Keywords to make it easy to search for your paper on databases.

To solidify your understanding of how to write an abstract, watch this 3-minute video from the University of Melbourne that takes you through a good example. Try not to get distracted by their awesome Australian accents.

Now if you would like more details, you can refer to this explanation.

12.3 The Real Last Step: Revise (and Revise and Revise)

The best writers revise (and revise and revise). Think back to Chapter 3: Writing Processes and the section on Revision. You need to think like your audience, which means you have to get out of your own head and think mindfully. One way to do this is to revise with purpose or in other words, with specific goals in mind.

You can't revise without a decent draft, so don't blow off the first draft deadline. The better your first draft, the better your paper will be in the end because you'll have enough time to really look at your paper. Actually re-look at your paper, or in other words, re-vise. Get it? Re-vision?

So how can you get out of your own head? Two ways: people and levels. The first way to get a fresh perspective is audience-oriented revision: peer review, teacher conferences, writing center appointments, and other outside feedback from real, live people.

Get Feedback!

When you find out how other people react to your paper, it will give you invaluable perspective into what's working and what's not. This is feedback and is extremely valuable. Your teacher should help you do these kinds of peer reviews and revisions in class.

Feedback can also come from anyone—friends, teachers, relatives, Writing Center tutors, roommates—just be sure to choose someone you trust who also knows about good writing and won't hesitate to tell you where you can improve. I don't know your grandma, but if she's the type of grandma who will tell you your paper is great no matter what's in it because you're just so nice, then run away! Okay, don't really run away from your grandma—she's probably very loving and supportive. Give her a hug instead. However, don't give your paper to your grandma to critique in that case. My grandma is actually a fantastic writer and wouldn't be afraid to tell me where I can improve. Do give your paper to someone like my grandma.

Here's a tip: Most universities have a Writing Center where you can take your paper to a Writing Tutor for help and feedback for free. Do it! It's free! And they can even meet with you online.

We're lucky at BYU that we even have our very own Social Science-specific Writing Center: the FHSS Writing Lab . They know Literature Reviews well and can help you with any stage of the writing process from selecting a topic to citing sources to synthesis. If you have more general writing questions (or if you need an appointment after 5pm), you can also go to the main BYU Research & Writing Center . They also offer online appointments. If you're not on our campus, look up your school's writing center.

As an undergrad, my husband didn't start out with the best writing skills, so he used to take his papers to the BYU Writing Center over and over and over. I think they made the rule that you can only go once a day because of him. And guess what? It helped! His grades went up! That was his secret to success that I'm passing on to you. Your teacher doesn't have time to personally meet with each student over and over and over, but the Writing Tutors are literally paid to do just that. Well, maybe keep your visits to only one per day, but you get what I mean. Take advantage! Make an appointment right now! Did I mention that it's free?

If you need more motivation to just do it, watch this "motivational" video by Shia Le Boeuf.

Revise by Levels

The second way to improve your paper is to go through a layered revision process focusing on global and then local issues. As you re-see your paper, take my advice and tackle Global Revision before you focus on Local Revision . What do I mean by that? Let me tell you a quick story.

A Revision Story Involving Cats

When my family and I were moving to our town, we looked at a lot of houses online. We fell in love with a beautiful old house that had been totally renovated but was selling at a shockingly low price. When we finally visited the house with our realtor, we discovered why it had been on the market for so long: it smelled like cat pee. Like really, really smelled. It turns out the house had been occupied by what many people would call a "crazy cat lady"—an older woman who lived with at least 50 cats. Then tragically, a fire completely destroyed the house (I'm pretty sure the woman and her cats survived).

The home owner used $400,000 of insurance money to beautifully restore the house. They rebuilt the intricate wooden staircase, restored the stately crown molding, installed lush carpet, and added upgrades to a gorgeous kitchen. The only problem was that they did their restoration in the wrong order—they took care of the local issues of paint color and carpet thickness while ignoring the more global issue of the smell. Eventually, they had to rip up all their work in the basement in order to treat the floor with a special enzyme that combated cat urine. If they'd just treated the cat smell first, then they could have saved themselves thousands of dollars, hours of work, and could have sold their house for a much higher price.

The Moral of the Story

What does all this have to do with revision? You've got it—treat the g lobal issues first! Get rid of the cat pee! Don't worry about local issues like flowery language or sentences that connect perfectly to each other if you're just going to have to completely renovate that section later. Work on the global issues like ideas, logical order, and evidence first and wait until those are intact before focusing on the details. Put another way, whole-paper and paragraph-level revisions should come before sentence-level and word-level changes.

As a final gift, fantastic BYU Family Science professor Julie Haupt offers the following path for doing four purposeful revisions—two global revisions and two local revisions. If you really want to improve your literature review, follow these steps.

GLOBAL REVISION—The Forest

Level 1: Structural Review (Global)

Purpose: The structural review examines the document as a whole to see if all requirements are met and the document’s organization is sound.

Meet Assignment Requirements. Ask yourself if your paper meets all the requirements of the assignment? Look at your structure and make sure you have all necessary sections such as the following:

Introduction (with Thesis Statement and/or Organizing Statement)

Body with Headings

Conclusion/Discussion

Include a Thesis and an Organizing Statement. Does the current version of the thesis statement match the tone, scope, and organization of the body text? Does an organizing statement after the thesis introduce the major topics and the order they will appear in the body (e.g., “In this review, I will first discuss . . . then . . . and finally . . .)

Level 2 (Global): Paragraph/Logic Review

Purpose: The Paragraph/Logic Review is designed to review each paragraph for cohesion and compliance to the CEC (Claim-Evidence-Commentary) format.

LOCAL REVISION—The Tree

Level 3 (Local): APA Formatting Review

Purpose: The APA Formatting Review is designed to make sure all APA conventions are explicitly followed to help the paper reflect a high level of professionalism.

Check Document Formatting. Do the title page, abstract, body text, and reference page appear in the correct page formatting as required? (Use the APA Manual if you have questions.)

Make a Final Check of the In-Text Citations. Is all information properly cited with an in-text citation when needed? Do all in-text citations include the year next to the author(s)? When more than one citation is listed within parentheses are they separated by semi-colons and ordered alphabetically by first author’s last name? If included in parentheses, do studies with multiple authors use ampersands ("&" rather than the word "and") before listing the last author?

Use “et al.” Correctly. If a study has three or more authors, do you include only the first author’s last name + et al. + publication year in in-text citations? Do you include all authors up to 20 in the References page? For any publications with 21 or more authors, do you include the first 19 authors' name, then insert an ellipsis ( . . . ), and then the last author's name?

Level 4 (Local): Finishing Review

Purpose: The Finishing Review is an opportunity to look closely at sentence construction, language, hedging (qualifying statements), and grammar/punctuation.

Review Phrasing with a Read-Aloud Session. Read your paper aloud. Since having to read a sentence twice to get its meaning or “tripping over” phrasing can be an indication of awkward construction, are all sentences easily read aloud? Are any sentences so long that they have become difficult to comprehend, but could be split without changing the meaning?

I know Literature Reviews can be daunting, but I hope that after reading this chapter you feel better prepared to tackle this bodacious writing assignment. As you practice writing, you'll find that it'll get easier and easier until it's as intuitive as riding a hoverboard.

*Bonus Video

If you're still confused or would like more guidance on writing a literature review, here is an optional 25-minute video that thoroughly goes through the entire process of writing a literature review. As an extra bonus, it's made by Michael Paye from the University of Dublin who has an awesome Irish accent. Enjoy!

Brigham Young University

Cristie Cowles Charles teaches writing and literature courses at Brigham Young University in Provo, Utah. She enjoys sparking a love for writing in her students--or at least a love for having had written (it's always worth it in the end, right?). She thinks pumpkin pie counts as a vegetable, is married to a super hot mechanical engineering and neuroscience professor (yes, they exist), and adores her five magnificent children.

Structure of a literature review

Determine your purpose.

Work out what you need to address in the literature review. What are you being asked to do in your literature review? What are you searching the literature to discover? Check your assignment question and your criteria sheet to know what to focus on.

Do an extensive search of the literature

Find out what has been written on the topic.

What kind of literature?

Select appropriate source material: Use a variety of academic or scholarly sources that are relevant, current and authoritative. An extensive review of relevant material will include — books, journal articles, reports, government documents, conference proceedings and web resources. The Library would be the best place to search for your sources.

How many resources?

The number of sources that you will be required to review will depend on what the literature review is for and how advanced you are in your studies. It could be from five sources at first year undergraduate level to more than fifty for a thesis. Your lecturer will advise you on these details.

Note the bibliographical details of your sources

Keep a note of the publication title, date, authors’ names, page numbers and publishers. These details will save you time later.

Read the literature

Critically read each source, look for the arguments presented rather than for facts.
Take notes as you read and start to organise your review around themes and ideas.
Consider using a table, matrix or concept map to identify how the different sources relate to each other.

Analyse the literature you have found

In order for your writing to reflect strong critical analysis, you need to evaluate the sources. For each source you are reviewing ask yourself these questions:

What are the key terms and concepts?
How relevant is this article to my specific topic?
What are the major relationships, trends and patterns?
How has the author structured the arguments?
How authoritative and credible is this source?
What are the differences and similarities between the sources?
Are there any gaps in the literature that require further study?

Write the review

Start by writing your thesis statement. This is an important introductory sentence that will tell your reader what the topic is and the overall perspective or argument you will be presenting.
Like essays, a literature review must have an introduction, a body and a conclusion.

Introduction

Your introduction should give an outline of:

why you are writing a review, and why the topic is important
the scope of the review — what aspects of the topic will be discussed
the criteria used for your literature selection (e.g. type of sources used, date range)
the organisational pattern of the review.

Body paragraphs

Each body paragraph should deal with a different theme that is relevant to your topic. You will need to synthesise several of your reviewed readings into each paragraph, so that there is a clear connection between the various sources. You will need to critically analyse each source for how they contribute to the themes you are researching.

The body could include paragraphs on:

historical background
methodologies
previous studies on the topic
mainstream versus alternative viewpoints
principal questions being asked
general conclusions that are being drawn.

Your conclusion should give a summary of:

the main agreements and disagreements in the literature
any gaps or areas for further research
your overall perspective on the topic.
outlined the purpose and scope?
identified appropriate and credible (academic/scholarly) literature?
recorded the bibliographical details of the sources?
analysed and critiqued your readings?
identified gaps in the literature and research?
explored methodologies / theories / hypotheses / models?
discussed the varying viewpoints?
written an introduction, body and conclusion?
checked punctuation and spelling?

Even though there are many methods for conducting a literature review and techniques for it, as presented in Chapter 13 , the actual writing is experienced as challenging, particularly by those new to research. This calls on skills how to write, how to express thoughts of others and how to keep one’s own voice. To support these skills for the actual writing, there are points of attention, techniques and tips that can help the writing to be more effective; this is the purpose of this chapter.

How do you do a literature review?

There is a problem in research. It exists in all fields. All researchers must deal with it, no matter their level. The problem is language. Because we use language when searching for research (articles, books, etc.), our results can be as biased, imperfect, and problematic as language itself!

This lesson will show you how academics research using scholarly databases and the techniques they use to avoid biases in their own words. Specifically, this guide will introduce you to using Subjects to generate useful results in scholarly databases.

For all examples, I use the mock research question, “How does microgravity impair astronauts' diet on the International Space Station?”
