What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

Search for relevant literature
Evaluate sources
Identify themes, debates, and gaps
Outline the structure
Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

Quick Run-through
Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

Demonstrate your familiarity with the topic and its scholarly context
Develop a theoretical framework and methodology for your research
Position your work in relation to other researchers and theorists
Show how your research addresses a gap or contributes to a debate
Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Prevent plagiarism. Run a free check.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
Body image, self-perception, self-esteem, mental health
Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

Your university’s library catalogue
Google Scholar
Project Muse (humanities and social sciences)
Medline (life sciences and biomedicine)
EconLit (economics)
Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

What question or problem is the author addressing?
What are the key concepts and how are they defined?
What are the key theories, models, and methods?
Does the research use established frameworks or take an innovative approach?
What are the results and conclusions of the study?
How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

Academic style
Vague sentences
Style consistency

See an example

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
Themes: what questions or concepts recur across the literature?
Debates, conflicts and contradictions: where do sources disagree?
Pivotal publications: are there any influential theories or studies that changed the direction of the field?
Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

Most research has focused on young women.
There is an increasing interest in the visual aspects of social media.
But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

Look at what results have emerged in qualitative versus quantitative research
Discuss how the topic has been approached by empirical versus theoretical scholarship
Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

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 sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

To familiarize yourself with the current state of knowledge on your topic
To ensure that you’re not just repeating what others have already done
To identify gaps in knowledge and unresolved problems that your research can address
To develop your theoretical framework and methodology
To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .

An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic.

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies:

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements.

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources.

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems.

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic.

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods.

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers. Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved. Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic. Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings. Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject. It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review: Introduction: Provide an overview of the topic. Define the scope and purpose of the literature review. State the research question or objective. Body: Organize the literature by themes, concepts, or chronology. Critically analyze and evaluate each source. Discuss the strengths and weaknesses of the studies. Highlight any methodological limitations or biases. Identify patterns, connections, or contradictions in the existing research. Conclusion: Summarize the key points discussed in the literature review. Highlight the research gap. Address the research question or objective stated in the introduction. Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:

	Annotated Bibliography	Literature Review
Purpose	List of citations of books, articles, and other sources with a brief description (annotation) of each source.	Comprehensive and critical analysis of existing literature on a specific topic.
Focus	Summary and evaluation of each source, including its relevance, methodology, and key findings.	Provides an overview of the current state of knowledge on a particular subject and identifies gaps, trends, and patterns in existing literature.
Structure	Each citation is followed by a concise paragraph (annotation) that describes the source’s content, methodology, and its contribution to the topic.	The literature review is organized thematically or chronologically and involves a synthesis of the findings from different sources to build a narrative or argument.
Length	Typically 100-200 words	Length of literature review ranges from a few pages to several chapters
Independence	Each source is treated separately, with less emphasis on synthesizing the information across sources.	The writer synthesizes information from multiple sources to present a cohesive overview of the topic.

Steps in Conducting a Literature Review

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question. That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment. Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

Explains the background of research on a topic.
Demonstrates why a topic is significant to a subject area.
Discovers relationships between research studies/ideas.
Identifies major themes, concepts, and researchers on a topic.
Identifies critical gaps and points of disagreement.
Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question. The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

Make sure your research question is not too broad or too narrow. Is it manageable?
Begin writing down terms that are related to your question. These will be useful for searches later.
If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover?

This may depend on your assignment. How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search.

Where to find databases:

use the tabs on this guide
Find other databases in the Nursing Information Resources web page
More on the Medical Library web page
... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
Review the abstracts of research studies carefully. This will save you time.
Use the bibliographies and references of research studies you find to locate others.
Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
Ask your librarian for help at any time.
Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

What was the research question of the study you are reviewing? What were the authors trying to discover?
Was the research funded by a source that could influence the findings?
What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
If there are conflicting studies, why do you think that is?
How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips:

Review the abstracts carefully.
Keep careful notes so that you may track your thought processes during the research process.
Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D. The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review? A literature could be written to accomplish different aims:

To develop a theory or evaluate an existing theory
To summarize the historical or existing state of a research topic
Identify a problem in a field of research

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews . Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

A research paper assigned in a course
A thesis or dissertation
A grant proposal
An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework: 10.1177/08948453211037398

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

Example : The effect of leave policies on increasing fertility: a systematic review: 10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

Example : Employment Instability and Fertility in Europe: A Meta-Analysis: 10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts . Journal of Advanced Nursing , 53 (3), 311-318.

Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis: 10.1177/05390184221113735

How to Write a Literature Review: Six Steps to Get You from Start to Finish

Writing-a-literature-review-six-steps-to-get-you-from-start-to-finish.

Tanya Golash-Boza, Associate Professor of Sociology, University of California

February 03, 2022

Writing a literature review is often the most daunting part of writing an article, book, thesis, or dissertation. “The literature” seems (and often is) massive. I have found it helpful to be as systematic as possible when completing this gargantuan task.

Sonja Foss and William Walters* describe an efficient and effective way of writing a literature review. Their system provides an excellent guide for getting through the massive amounts of literature for any purpose: in a dissertation, an M.A. thesis, or preparing a research article for publication in any field of study. Below is a summary of the steps they outline as well as a step-by-step method for writing a literature review.

How to Write a Literature Review

Step One: Decide on your areas of research:

Before you begin to search for articles or books, decide beforehand what areas you are going to research. Make sure that you only get articles and books in those areas, even if you come across fascinating books in other areas. A literature review I am currently working on, for example, explores barriers to higher education for undocumented students.

Step Two: Search for the literature:

Conduct a comprehensive bibliographic search of books and articles in your area. Read the abstracts online and download and/or print those articles that pertain to your area of research. Find books in the library that are relevant and check them out. Set a specific time frame for how long you will search. It should not take more than two or three dedicated sessions.

Step Three: Find relevant excerpts in your books and articles:

Skim the contents of each book and article and look specifically for these five things:

1. Claims, conclusions, and findings about the constructs you are investigating

2. Definitions of terms

3. Calls for follow-up studies relevant to your project

4. Gaps you notice in the literature

5. Disagreement about the constructs you are investigating

When you find any of these five things, type the relevant excerpt directly into a Word document. Don’t summarize, as summarizing takes longer than simply typing the excerpt. Make sure to note the name of the author and the page number following each excerpt. Do this for each article and book that you have in your stack of literature. When you are done, print out your excerpts.

Step Four: Code the literature:

Get out a pair of scissors and cut each excerpt out. Now, sort the pieces of paper into similar topics. Figure out what the main themes are. Place each excerpt into a themed pile. Make sure each note goes into a pile. If there are excerpts that you can’t figure out where they belong, separate those and go over them again at the end to see if you need new categories. When you finish, place each stack of notes into an envelope labeled with the name of the theme.

Step Five: Create Your Conceptual Schema:

Type, in large font, the name of each of your coded themes. Print this out, and cut the titles into individual slips of paper. Take the slips of paper to a table or large workspace and figure out the best way to organize them. Are there ideas that go together or that are in dialogue with each other? Are there ideas that contradict each other? Move around the slips of paper until you come up with a way of organizing the codes that makes sense. Write the conceptual schema down before you forget or someone cleans up your slips of paper.

Step Six: Begin to Write Your Literature Review:

Choose any section of your conceptual schema to begin with. You can begin anywhere, because you already know the order. Find the envelope with the excerpts in them and lay them on the table in front of you. Figure out a mini-conceptual schema based on that theme by grouping together those excerpts that say the same thing. Use that mini-conceptual schema to write up your literature review based on the excerpts that you have in front of you. Don’t forget to include the citations as you write, so as not to lose track of who said what. Repeat this for each section of your literature review.

Once you complete these six steps, you will have a complete draft of your literature review. The great thing about this process is that it breaks down into manageable steps something that seems enormous: writing a literature review.

I think that Foss and Walter’s system for writing the literature review is ideal for a dissertation, because a Ph.D. candidate has already read widely in his or her field through graduate seminars and comprehensive exams.

It may be more challenging for M.A. students, unless you are already familiar with the literature. It is always hard to figure out how much you need to read for deep meaning, and how much you just need to know what others have said. That balance will depend on how much you already know.

For people writing literature reviews for articles or books, this system also could work, especially when you are writing in a field with which you are already familiar. The mere fact of having a system can make the literature review seem much less daunting, so I recommend this system for anyone who feels overwhelmed by the prospect of writing a literature review.

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

There are five key steps to writing a literature review:

Search for relevant literature
Evaluate sources
Identify themes, debates and gaps
Outline the structure
Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

Quick Run-through
Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

Demonstrate your familiarity with the topic and scholarly context
Develop a theoretical framework and methodology for your research
Position yourself in relation to other researchers and theorists
Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Prevent plagiarism, run a free check.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
Body image, self-perception, self-esteem, mental health
Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

Your university’s library catalogue
Google Scholar
Project Muse (humanities and social sciences)
Medline (life sciences and biomedicine)
EconLit (economics)
Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

What question or problem is the author addressing?
What are the key concepts and how are they defined?
What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
What are the results and conclusions of the study?
How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
Themes: what questions or concepts recur across the literature?
Debates, conflicts and contradictions: where do sources disagree?
Pivotal publications: are there any influential theories or studies that changed the direction of the field?
Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

Most research has focused on young women.
There is an increasing interest in the visual aspects of social media.
But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

Methodological

Look at what results have emerged in qualitative versus quantitative research
Discuss how the topic has been approached by empirical versus theoretical scholarship
Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, 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 transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

To familiarise yourself with the current state of knowledge on your topic
To ensure that you’re not just repeating what others have already done
To identify gaps in knowledge and unresolved problems that your research can address
To develop your theoretical framework and methodology
To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

How To Write An A-Grade Literature Review

3 straightforward steps (with examples) + free template.

By: Derek Jansen (MBA) | Expert Reviewed By: Dr. Eunice Rautenbach | October 2019

Quality research is about building onto the existing work of others , “standing on the shoulders of giants”, as Newton put it. The literature review chapter of your dissertation, thesis or research project is where you synthesise this prior work and lay the theoretical foundation for your own research.

Long story short, this chapter is a pretty big deal, which is why you want to make sure you get it right . In this post, I’ll show you exactly how to write a literature review in three straightforward steps, so you can conquer this vital chapter (the smart way).

Overview: The Literature Review Process

Understanding the “ why “
Finding the relevant literature
Cataloguing and synthesising the information
Outlining & writing up your literature review
Example of a literature review

But first, the “why”…

Before we unpack how to write the literature review chapter, we’ve got to look at the why . To put it bluntly, if you don’t understand the function and purpose of the literature review process, there’s no way you can pull it off well. So, what exactly is the purpose of the literature review?

Well, there are (at least) four core functions:

For you to gain an understanding (and demonstrate this understanding) of where the research is at currently, what the key arguments and disagreements are.
For you to identify the gap(s) in the literature and then use this as justification for your own research topic.
To help you build a conceptual framework for empirical testing (if applicable to your research topic).
To inform your methodological choices and help you source tried and tested questionnaires (for interviews ) and measurement instruments (for surveys ).

Most students understand the first point but don’t give any thought to the rest. To get the most from the literature review process, you must keep all four points front of mind as you review the literature (more on this shortly), or you’ll land up with a wonky foundation.

Okay – with the why out the way, let’s move on to the how . As mentioned above, writing your literature review is a process, which I’ll break down into three steps:

Finding the most suitable literature
Understanding , distilling and organising the literature
Planning and writing up your literature review chapter

Importantly, you must complete steps one and two before you start writing up your chapter. I know it’s very tempting, but don’t try to kill two birds with one stone and write as you read. You’ll invariably end up wasting huge amounts of time re-writing and re-shaping, or you’ll just land up with a disjointed, hard-to-digest mess . Instead, you need to read first and distil the information, then plan and execute the writing.

Step 1: Find the relevant literature

Naturally, the first step in the literature review journey is to hunt down the existing research that’s relevant to your topic. While you probably already have a decent base of this from your research proposal , you need to expand on this substantially in the dissertation or thesis itself.

Essentially, you need to be looking for any existing literature that potentially helps you answer your research question (or develop it, if that’s not yet pinned down). There are numerous ways to find relevant literature, but I’ll cover my top four tactics here. I’d suggest combining all four methods to ensure that nothing slips past you:

Method 1 – Google Scholar Scrubbing

Google’s academic search engine, Google Scholar , is a great starting point as it provides a good high-level view of the relevant journal articles for whatever keyword you throw at it. Most valuably, it tells you how many times each article has been cited, which gives you an idea of how credible (or at least, popular) it is. Some articles will be free to access, while others will require an account, which brings us to the next method.

Method 2 – University Database Scrounging

Generally, universities provide students with access to an online library, which provides access to many (but not all) of the major journals.

So, if you find an article using Google Scholar that requires paid access (which is quite likely), search for that article in your university’s database – if it’s listed there, you’ll have access. Note that, generally, the search engine capabilities of these databases are poor, so make sure you search for the exact article name, or you might not find it.

Method 3 – Journal Article Snowballing

At the end of every academic journal article, you’ll find a list of references. As with any academic writing, these references are the building blocks of the article, so if the article is relevant to your topic, there’s a good chance a portion of the referenced works will be too. Do a quick scan of the titles and see what seems relevant, then search for the relevant ones in your university’s database.

Method 4 – Dissertation Scavenging

Similar to Method 3 above, you can leverage other students’ dissertations. All you have to do is skim through literature review chapters of existing dissertations related to your topic and you’ll find a gold mine of potential literature. Usually, your university will provide you with access to previous students’ dissertations, but you can also find a much larger selection in the following databases:

Open Access Theses & Dissertations
Stanford SearchWorks

Keep in mind that dissertations and theses are not as academically sound as published, peer-reviewed journal articles (because they’re written by students, not professionals), so be sure to check the credibility of any sources you find using this method. You can do this by assessing the citation count of any given article in Google Scholar. If you need help with assessing the credibility of any article, or with finding relevant research in general, you can chat with one of our Research Specialists .

Alright – with a good base of literature firmly under your belt, it’s time to move onto the next step.

Need a helping hand?

Step 2: Log, catalogue and synthesise

Once you’ve built a little treasure trove of articles, it’s time to get reading and start digesting the information – what does it all mean?

While I present steps one and two (hunting and digesting) as sequential, in reality, it’s more of a back-and-forth tango – you’ll read a little , then have an idea, spot a new citation, or a new potential variable, and then go back to searching for articles. This is perfectly natural – through the reading process, your thoughts will develop , new avenues might crop up, and directional adjustments might arise. This is, after all, one of the main purposes of the literature review process (i.e. to familiarise yourself with the current state of research in your field).

As you’re working through your treasure chest, it’s essential that you simultaneously start organising the information. There are three aspects to this:

Logging reference information
Building an organised catalogue
Distilling and synthesising the information

I’ll discuss each of these below:

2.1 – Log the reference information

As you read each article, you should add it to your reference management software. I usually recommend Mendeley for this purpose (see the Mendeley 101 video below), but you can use whichever software you’re comfortable with. Most importantly, make sure you load EVERY article you read into your reference manager, even if it doesn’t seem very relevant at the time.

2.2 – Build an organised catalogue

In the beginning, you might feel confident that you can remember who said what, where, and what their main arguments were. Trust me, you won’t. If you do a thorough review of the relevant literature (as you must!), you’re going to read many, many articles, and it’s simply impossible to remember who said what, when, and in what context . Also, without the bird’s eye view that a catalogue provides, you’ll miss connections between various articles, and have no view of how the research developed over time. Simply put, it’s essential to build your own catalogue of the literature.

I would suggest using Excel to build your catalogue, as it allows you to run filters, colour code and sort – all very useful when your list grows large (which it will). How you lay your spreadsheet out is up to you, but I’d suggest you have the following columns (at minimum):

Author, date, title – Start with three columns containing this core information. This will make it easy for you to search for titles with certain words, order research by date, or group by author.
Categories or keywords – You can either create multiple columns, one for each category/theme and then tick the relevant categories, or you can have one column with keywords.
Key arguments/points – Use this column to succinctly convey the essence of the article, the key arguments and implications thereof for your research.
Context – Note the socioeconomic context in which the research was undertaken. For example, US-based, respondents aged 25-35, lower- income, etc. This will be useful for making an argument about gaps in the research.
Methodology – Note which methodology was used and why. Also, note any issues you feel arise due to the methodology. Again, you can use this to make an argument about gaps in the research.
Quotations – Note down any quoteworthy lines you feel might be useful later.
Notes – Make notes about anything not already covered. For example, linkages to or disagreements with other theories, questions raised but unanswered, shortcomings or limitations, and so forth.

If you’d like, you can try out our free catalog template here (see screenshot below).

2.3 – Digest and synthesise

Most importantly, as you work through the literature and build your catalogue, you need to synthesise all the information in your own mind – how does it all fit together? Look for links between the various articles and try to develop a bigger picture view of the state of the research. Some important questions to ask yourself are:

What answers does the existing research provide to my own research questions ?
Which points do the researchers agree (and disagree) on?
How has the research developed over time?
Where do the gaps in the current research lie?

To help you develop a big-picture view and synthesise all the information, you might find mind mapping software such as Freemind useful. Alternatively, if you’re a fan of physical note-taking, investing in a large whiteboard might work for you.

Mind mapping is a useful way to plan your literature review.

Step 3: Outline and write it up!

Once you’re satisfied that you have digested and distilled all the relevant literature in your mind, it’s time to put pen to paper (or rather, fingers to keyboard). There are two steps here – outlining and writing:

3.1 – Draw up your outline

Having spent so much time reading, it might be tempting to just start writing up without a clear structure in mind. However, it’s critically important to decide on your structure and develop a detailed outline before you write anything. Your literature review chapter needs to present a clear, logical and an easy to follow narrative – and that requires some planning. Don’t try to wing it!

Naturally, you won’t always follow the plan to the letter, but without a detailed outline, you’re more than likely going to end up with a disjointed pile of waffle , and then you’re going to spend a far greater amount of time re-writing, hacking and patching. The adage, “measure twice, cut once” is very suitable here.

In terms of structure, the first decision you’ll have to make is whether you’ll lay out your review thematically (into themes) or chronologically (by date/period). The right choice depends on your topic, research objectives and research questions, which we discuss in this article .

Once that’s decided, you need to draw up an outline of your entire chapter in bullet point format. Try to get as detailed as possible, so that you know exactly what you’ll cover where, how each section will connect to the next, and how your entire argument will develop throughout the chapter. Also, at this stage, it’s a good idea to allocate rough word count limits for each section, so that you can identify word count problems before you’ve spent weeks or months writing!

3.2 – Get writing

With a detailed outline at your side, it’s time to start writing up (finally!). At this stage, it’s common to feel a bit of writer’s block and find yourself procrastinating under the pressure of finally having to put something on paper. To help with this, remember that the objective of the first draft is not perfection – it’s simply to get your thoughts out of your head and onto paper, after which you can refine them. The structure might change a little, the word count allocations might shift and shuffle, and you might add or remove a section – that’s all okay. Don’t worry about all this on your first draft – just get your thoughts down on paper.

Once you’ve got a full first draft (however rough it may be), step away from it for a day or two (longer if you can) and then come back at it with fresh eyes. Pay particular attention to the flow and narrative – does it fall fit together and flow from one section to another smoothly? Now’s the time to try to improve the linkage from each section to the next, tighten up the writing to be more concise, trim down word count and sand it down into a more digestible read.

Once you’ve done that, give your writing to a friend or colleague who is not a subject matter expert and ask them if they understand the overall discussion. The best way to assess this is to ask them to explain the chapter back to you. This technique will give you a strong indication of which points were clearly communicated and which weren’t. If you’re working with Grad Coach, this is a good time to have your Research Specialist review your chapter.

Finally, tighten it up and send it off to your supervisor for comment. Some might argue that you should be sending your work to your supervisor sooner than this (indeed your university might formally require this), but in my experience, supervisors are extremely short on time (and often patience), so, the more refined your chapter is, the less time they’ll waste on addressing basic issues (which you know about already) and the more time they’ll spend on valuable feedback that will increase your mark-earning potential.

Literature Review Example

In the video below, we unpack an actual literature review so that you can see how all the core components come together in reality.

Let’s Recap

In this post, we’ve covered how to research and write up a high-quality literature review chapter. Let’s do a quick recap of the key takeaways:

It is essential to understand the WHY of the literature review before you read or write anything. Make sure you understand the 4 core functions of the process.
The first step is to hunt down the relevant literature . You can do this using Google Scholar, your university database, the snowballing technique and by reviewing other dissertations and theses.
Next, you need to log all the articles in your reference manager , build your own catalogue of literature and synthesise all the research.
Following that, you need to develop a detailed outline of your entire chapter – the more detail the better. Don’t start writing without a clear outline (on paper, not in your head!)
Write up your first draft in rough form – don’t aim for perfection. Remember, done beats perfect.
Refine your second draft and get a layman’s perspective on it . Then tighten it up and submit it to your supervisor.

Psst… there’s more!

How To Write A Literature Review - A Complete Guide

A literature review is much more than just another section in your research paper. It forms the very foundation of your research. It is a formal piece of writing where you analyze the existing theoretical framework, principles, and assumptions and use that as a base to shape your approach to the research question.

Curating and drafting a solid literature review section not only lends more credibility to your research paper but also makes your research tighter and better focused. But, writing literature reviews is a difficult task. It requires extensive reading, plus you have to consider market trends and technological and political changes, which tend to change in the blink of an eye.

Now streamline your literature review process with the help of SciSpace Copilot. With this AI research assistant, you can efficiently synthesize and analyze a vast amount of information, identify key themes and trends, and uncover gaps in the existing research. Get real-time explanations, summaries, and answers to your questions for the paper you're reviewing, making navigating and understanding the complex literature landscape easier.

Perform Literature reviews using SciSpace Copilot

In this comprehensive guide, we will explore everything from the definition of a literature review, its appropriate length, various types of literature reviews, and how to write one.

What is a literature review?

A literature review is a collation of survey, research, critical evaluation, and assessment of the existing literature in a preferred domain.

Eminent researcher and academic Arlene Fink, in her book Conducting Research Literature Reviews , defines it as the following:

“A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.

Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic, and to demonstrate to your readers how your research fits within a larger field of study.”

Simply put, a literature review can be defined as a critical discussion of relevant pre-existing research around your research question and carving out a definitive place for your study in the existing body of knowledge. Literature reviews can be presented in multiple ways: a section of an article, the whole research paper itself, or a chapter of your thesis.

A literature review does function as a summary of sources, but it also allows you to analyze further, interpret, and examine the stated theories, methods, viewpoints, and, of course, the gaps in the existing content.

As an author, you can discuss and interpret the research question and its various aspects and debate your adopted methods to support the claim.

What is the purpose of a literature review?

A literature review is meant to help your readers understand the relevance of your research question and where it fits within the existing body of knowledge. As a researcher, you should use it to set the context, build your argument, and establish the need for your study.

What is the importance of a literature review?

The literature review is a critical part of research papers because it helps you:

Gain an in-depth understanding of your research question and the surrounding area
Convey that you have a thorough understanding of your research area and are up-to-date with the latest changes and advancements
Establish how your research is connected or builds on the existing body of knowledge and how it could contribute to further research
Elaborate on the validity and suitability of your theoretical framework and research methodology
Identify and highlight gaps and shortcomings in the existing body of knowledge and how things need to change
Convey to readers how your study is different or how it contributes to the research area

How long should a literature review be?

Ideally, the literature review should take up 15%-40% of the total length of your manuscript. So, if you have a 10,000-word research paper, the minimum word count could be 1500.

Your literature review format depends heavily on the kind of manuscript you are writing — an entire chapter in case of doctoral theses, a part of the introductory section in a research article, to a full-fledged review article that examines the previously published research on a topic.

Another determining factor is the type of research you are doing. The literature review section tends to be longer for secondary research projects than primary research projects.

What are the different types of literature reviews?

All literature reviews are not the same. There are a variety of possible approaches that you can take. It all depends on the type of research you are pursuing.

Here are the different types of literature reviews:

Argumentative review

It is called an argumentative review when you carefully present literature that only supports or counters a specific argument or premise to establish a viewpoint.

Integrative review

It is a type of literature review focused on building a comprehensive understanding of a topic by combining available theoretical frameworks and empirical evidence.

Methodological review

This approach delves into the ''how'' and the ''what" of the research question — you cannot look at the outcome in isolation; you should also review the methodology used.

Systematic review

This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research and collect, report, and analyze data from the studies included in the review.

Meta-analysis review

Meta-analysis uses statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects than those derived from the individual studies included within a review.

Historical review

Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and identify future research's likely directions.

Theoretical Review

This form aims to examine the corpus of theory accumulated regarding an issue, concept, theory, and phenomenon. The theoretical literature review helps to establish what theories exist, the relationships between them, the degree the existing approaches have been investigated, and to develop new hypotheses to be tested.

Scoping Review

The Scoping Review is often used at the beginning of an article, dissertation, or research proposal. It is conducted before the research to highlight gaps in the existing body of knowledge and explains why the project should be greenlit.

State-of-the-Art Review

The State-of-the-Art review is conducted periodically, focusing on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic and highlights where there are still disagreements.

Can you use the first person in a literature review?

When writing literature reviews, you should avoid the usage of first-person pronouns. It means that instead of "I argue that" or "we argue that," the appropriate expression would be "this research paper argues that."

Do you need an abstract for a literature review?

Ideally, yes. It is always good to have a condensed summary that is self-contained and independent of the rest of your review. As for how to draft one, you can follow the same fundamental idea when preparing an abstract for a literature review. It should also include:

The research topic and your motivation behind selecting it
A one-sentence thesis statement
An explanation of the kinds of literature featured in the review
Summary of what you've learned
Conclusions you drew from the literature you reviewed
Potential implications and future scope for research

Here's an example of the abstract of a literature review

Is a literature review written in the past tense?

Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present perfect tenses.

How many sources for a literature review?

There are multiple approaches to deciding how many sources to include in a literature review section. The first approach would be to look level you are at as a researcher. For instance, a doctoral thesis might need 60+ sources. In contrast, you might only need to refer to 5-15 sources at the undergraduate level.

The second approach is based on the kind of literature review you are doing — whether it is merely a chapter of your paper or if it is a self-contained paper in itself. When it is just a chapter, sources should equal the total number of pages in your article's body. In the second scenario, you need at least three times as many sources as there are pages in your work.

Quick tips on how to write a literature review

To know how to write a literature review, you must clearly understand its impact and role in establishing your work as substantive research material.

You need to follow the below-mentioned steps, to write a literature review:

Outline the purpose behind the literature review
Search relevant literature
Examine and assess the relevant resources
Discover connections by drawing deep insights from the resources
Structure planning to write a good literature review

1. Outline and identify the purpose of a literature review

As a first step on how to write a literature review, you must know what the research question or topic is and what shape you want your literature review to take. Ensure you understand the research topic inside out, or else seek clarifications. You must be able to the answer below questions before you start:

How many sources do I need to include?
What kind of sources should I analyze?
How much should I critically evaluate each source?
Should I summarize, synthesize or offer a critique of the sources?
Do I need to include any background information or definitions?

Additionally, you should know that the narrower your research topic is, the swifter it will be for you to restrict the number of sources to be analyzed.

2. Search relevant literature

Dig deeper into search engines to discover what has already been published around your chosen topic. Make sure you thoroughly go through appropriate reference sources like books, reports, journal articles, government docs, and web-based resources.

You must prepare a list of keywords and their different variations. You can start your search from any library’s catalog, provided you are an active member of that institution. The exact keywords can be extended to widen your research over other databases and academic search engines like:

Google Scholar
Microsoft Academic
Science.gov

Besides, it is not advisable to go through every resource word by word. Alternatively, what you can do is you can start by reading the abstract and then decide whether that source is relevant to your research or not.

Additionally, you must spend surplus time assessing the quality and relevance of resources. It would help if you tried preparing a list of citations to ensure that there lies no repetition of authors, publications, or articles in the literature review.

3. Examine and assess the sources

It is nearly impossible for you to go through every detail in the research article. So rather than trying to fetch every detail, you have to analyze and decide which research sources resemble closest and appear relevant to your chosen domain.

While analyzing the sources, you should look to find out answers to questions like:

What question or problem has the author been describing and debating?
What is the definition of critical aspects?
How well the theories, approach, and methodology have been explained?
Whether the research theory used some conventional or new innovative approach?
How relevant are the key findings of the work?
In what ways does it relate to other sources on the same topic?
What challenges does this research paper pose to the existing theory
What are the possible contributions or benefits it adds to the subject domain?

Be always mindful that you refer only to credible and authentic resources. It would be best if you always take references from different publications to validate your theory.

Always keep track of important information or data you can present in your literature review right from the beginning. It will help steer your path from any threats of plagiarism and also make it easier to curate an annotated bibliography or reference section.

4. Discover connections

At this stage, you must start deciding on the argument and structure of your literature review. To accomplish this, you must discover and identify the relations and connections between various resources while drafting your abstract.

A few aspects that you should be aware of while writing a literature review include:

Rise to prominence: Theories and methods that have gained reputation and supporters over time.
Constant scrutiny: Concepts or theories that repeatedly went under examination.
Contradictions and conflicts: Theories, both the supporting and the contradictory ones, for the research topic.
Knowledge gaps: What exactly does it fail to address, and how to bridge them with further research?
Influential resources: Significant research projects available that have been upheld as milestones or perhaps, something that can modify the current trends

Once you join the dots between various past research works, it will be easier for you to draw a conclusion and identify your contribution to the existing knowledge base.

5. Structure planning to write a good literature review

There exist different ways towards planning and executing the structure of a literature review. The format of a literature review varies and depends upon the length of the research.

Like any other research paper, the literature review format must contain three sections: introduction, body, and conclusion. The goals and objectives of the research question determine what goes inside these three sections.

Nevertheless, a good literature review can be structured according to the chronological, thematic, methodological, or theoretical framework approach.

Organize the literature review into sections that present themes or identify trends, including relevant theory. You are not trying to list all the material published, but to synthesize and evaluate it according to the guiding concept of your thesis or research question.

What is a literature review?

A literature review is an account of what has been published on a topic by accredited scholars and researchers. Occasionally you will be asked to write one as a separate assignment, but more often it is part of the introduction to an essay, research report, or thesis. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries

A literature review must do these things:

be organized around and related directly to the thesis or research question you are developing
synthesize results into a summary of what is and is not known
identify areas of controversy in the literature
formulate questions that need further research

Ask yourself questions like these:

What is the specific thesis, problem, or research question that my literature review helps to define?
What type of literature review am I conducting? Am I looking at issues of theory? methodology? policy? quantitative research (e.g. on the effectiveness of a new procedure)? qualitative research (e.g., studies of loneliness among migrant workers)?
What is the scope of my literature review? What types of publications am I using (e.g., journals, books, government documents, popular media)? What discipline am I working in (e.g., nursing psychology, sociology, medicine)?
How good was my information seeking? Has my search been wide enough to ensure I've found all the relevant material? Has it been narrow enough to exclude irrelevant material? Is the number of sources I've used appropriate for the length of my paper?
Have I critically analyzed the literature I use? Do I follow through a set of concepts and questions, comparing items to each other in the ways they deal with them? Instead of just listing and summarizing items, do I assess them, discussing strengths and weaknesses?
Have I cited and discussed studies contrary to my perspective?
Will the reader find my literature review relevant, appropriate, and useful?

Ask yourself questions like these about each book or article you include:

Has the author formulated a problem/issue?
Is it clearly defined? Is its significance (scope, severity, relevance) clearly established?
Could the problem have been approached more effectively from another perspective?
What is the author's research orientation (e.g., interpretive, critical science, combination)?
What is the author's theoretical framework (e.g., psychological, developmental, feminist)?
What is the relationship between the theoretical and research perspectives?
Has the author evaluated the literature relevant to the problem/issue? Does the author include literature taking positions she or he does not agree with?
In a research study, how good are the basic components of the study design (e.g., population, intervention, outcome)? How accurate and valid are the measurements? Is the analysis of the data accurate and relevant to the research question? Are the conclusions validly based upon the data and analysis?
In material written for a popular readership, does the author use appeals to emotion, one-sided examples, or rhetorically-charged language and tone? Is there an objective basis to the reasoning, or is the author merely "proving" what he or she already believes?
How does the author structure the argument? Can you "deconstruct" the flow of the argument to see whether or where it breaks down logically (e.g., in establishing cause-effect relationships)?
In what ways does this book or article contribute to our understanding of the problem under study, and in what ways is it useful for practice? What are the strengths and limitations?
How does this book or article relate to the specific thesis or question I am developing?

How to Write a Literature Review

What is a literature review.

What Is the Literature
Writing the Review

A literature review is much more than an annotated bibliography or a list of separate reviews of articles and books. It is a critical, analytical summary and synthesis of the current knowledge of a topic. Thus it should compare and relate different theories, findings, etc, rather than just summarize them individually. In addition, it should have a particular focus or theme to organize the review. It does not have to be an exhaustive account of everything published on the topic, but it should discuss all the significant academic literature and other relevant sources important for that focus.

This is meant to be a general guide to writing a literature review: ways to structure one, what to include, how it supplements other research. For more specific help on writing a review, and especially for help on finding the literature to review, sign up for a Personal Research Session .

The specific organization of a literature review depends on the type and purpose of the review, as well as on the specific field or topic being reviewed. But in general, it is a relatively brief but thorough exploration of past and current work on a topic. Rather than a chronological listing of previous work, though, literature reviews are usually organized thematically, such as different theoretical approaches, methodologies, or specific issues or concepts involved in the topic. A thematic organization makes it much easier to examine contrasting perspectives, theoretical approaches, methodologies, findings, etc, and to analyze the strengths and weaknesses of, and point out any gaps in, previous research. And this is the heart of what a literature review is about. A literature review may offer new interpretations, theoretical approaches, or other ideas; if it is part of a research proposal or report it should demonstrate the relationship of the proposed or reported research to others' work; but whatever else it does, it must provide a critical overview of the current state of research efforts.

Literature reviews are common and very important in the sciences and social sciences. They are less common and have a less important role in the humanities, but they do have a place, especially stand-alone reviews.

Types of Literature Reviews

There are different types of literature reviews, and different purposes for writing a review, but the most common are:

Stand-alone literature review articles . These provide an overview and analysis of the current state of research on a topic or question. The goal is to evaluate and compare previous research on a topic to provide an analysis of what is currently known, and also to reveal controversies, weaknesses, and gaps in current work, thus pointing to directions for future research. You can find examples published in any number of academic journals, but there is a series of Annual Reviews of *Subject* which are specifically devoted to literature review articles. Writing a stand-alone review is often an effective way to get a good handle on a topic and to develop ideas for your own research program. For example, contrasting theoretical approaches or conflicting interpretations of findings can be the basis of your research project: can you find evidence supporting one interpretation against another, or can you propose an alternative interpretation that overcomes their limitations?
Part of a research proposal . This could be a proposal for a PhD dissertation, a senior thesis, or a class project. It could also be a submission for a grant. The literature review, by pointing out the current issues and questions concerning a topic, is a crucial part of demonstrating how your proposed research will contribute to the field, and thus of convincing your thesis committee to allow you to pursue the topic of your interest or a funding agency to pay for your research efforts.
Part of a research report . When you finish your research and write your thesis or paper to present your findings, it should include a literature review to provide the context to which your work is a contribution. Your report, in addition to detailing the methods, results, etc. of your research, should show how your work relates to others' work.

A literature review for a research report is often a revision of the review for a research proposal, which can be a revision of a stand-alone review. Each revision should be a fairly extensive revision. With the increased knowledge of and experience in the topic as you proceed, your understanding of the topic will increase. Thus, you will be in a better position to analyze and critique the literature. In addition, your focus will change as you proceed in your research. Some areas of the literature you initially reviewed will be marginal or irrelevant for your eventual research, and you will need to explore other areas more thoroughly.

Examples of Literature Reviews

See the series of Annual Reviews of *Subject* which are specifically devoted to literature review articles to find many examples of stand-alone literature reviews in the biomedical, physical, and social sciences.

Research report articles vary in how they are organized, but a common general structure is to have sections such as:

Abstract - Brief summary of the contents of the article
Introduction - A explanation of the purpose of the study, a statement of the research question(s) the study intends to address
Literature review - A critical assessment of the work done so far on this topic, to show how the current study relates to what has already been done
Methods - How the study was carried out (e.g. instruments or equipment, procedures, methods to gather and analyze data)
Results - What was found in the course of the study
Discussion - What do the results mean
Conclusion - State the conclusions and implications of the results, and discuss how it relates to the work reviewed in the literature review; also, point to directions for further work in the area

Here are some articles that illustrate variations on this theme. There is no need to read the entire articles (unless the contents interest you); just quickly browse through to see the sections, and see how each section is introduced and what is contained in them.

The Determinants of Undergraduate Grade Point Average: The Relative Importance of Family Background, High School Resources, and Peer Group Effects , in The Journal of Human Resources , v. 34 no. 2 (Spring 1999), p. 268-293.

This article has a standard breakdown of sections:

Introduction
Literature Review
Some discussion sections

First Encounters of the Bureaucratic Kind: Early Freshman Experiences with a Campus Bureaucracy , in The Journal of Higher Education , v. 67 no. 6 (Nov-Dec 1996), p. 660-691.

This one does not have a section specifically labeled as a "literature review" or "review of the literature," but the first few sections cite a long list of other sources discussing previous research in the area before the authors present their own study they are reporting.

What is a Literature Review?
Six Steps to Writing a Literature Review

Try A Citation Manager
Avoiding Plagiarism

Selecting a Research Topic

The first step in the process involves exploring and selecting a topic. You may revise the topic/scope of your research as you learn more from the literature. Be sure to select a topic that you are willing to work with for a considerable amount of time.

When thinking about a topic, it is important to consider the following:

Does the topic interest you?

Working on something that doesn’t excite you will make the process tedious. The research content should reflect your passion for research so it is essential to research in your area of interest rather than choosing a topic that interests someone else. While developing your research topic, broaden your thinking and creativity to determine what works best for you. Consider an area of high importance to your profession, or identify a gap in the research. It may take some time to narrow down on a topic and get started, but it’s worth the effort.

Is the Topic Relevant?

Be sure your subject meets the assignment/research requirements. When in doubt, review the guidelines and seek clarification from your professor.

What is the Scope and Purpose?

Sometimes your chosen topic may be too broad. To find direction, try limiting the scope and purpose of the research by identifying the concepts you wish to explore. Once this is accomplished, you can fine-tune your topic by experimenting with keyword searches our A-Z Databases until you are satisfied with your retrieval results.

Are there Enough Resources to Support Your Research?

If the topic is too narrow, you may not be able to provide the depth of results needed. When selecting a topic make sure you have adequate material to help with the research. Explore a variety of resources: journals, books, and online information.

Adapted from https://jgateplus.com/home/2018/10/11/the-dos-of-choosing-a-research-topic-part-1/

Why use keywords to search?

Library databases work differently than Google. Library databases work best when you search for concepts and keywords.
For your research, you will want to brainstorm keywords related to your research question. These keywords can lead you to relevant sources that you can use to start your research project.
Identify those terms relevant to your research and add 2-3 in the search box.

Now its time to decide whether or not to incorporate what you have found into your literature review. E valuate your resources to make sure they contain information that is authoritative, reliable, relevant and the most useful in supporting your research.

Remember to be:

Objective : keep an open mind
Unbiased : Consider all viewpoints, and include all sides of an argument, even ones that don't support your own

Criteria for Evaluating Research Publications

Significance and Contribution to the Field

• What is the author’s aim?

• To what extent has this aim been achieved?

• What does this text add to the body of knowledge? (theory, data and/or practical application)

• What relationship does it bear to other works in the field?

• What is missing/not stated?

• Is this a problem?

Methodology or Approach (Formal, research-based texts)

• What approach was used for the research? (eg; quantitative or qualitative, analysis/review of theory or current practice, comparative, case study, personal reflection etc…)

• How objective/biased is the approach?

• Are the results valid and reliable?

• What analytical framework is used to discuss the results?

Argument and Use of Evidence

• Is there a clear problem, statement or hypothesis?

• What claims are made?

• Is the argument consistent?

• What kinds of evidence does the text rely on?

• How valid and reliable is the evidence?

• How effective is the evidence in supporting the argument?

• What conclusions are drawn?

• Are these conclusions justified?

Writing Style and Text Structure

• Does the writing style suit the intended audience? (eg; expert/non-expert, academic/non- academic)

• What is the organizing principle of the text?

Could it be better organized?

Analysis: the Starting Point for Further Analysis & Inquiry

After evaluating your retrieved sources you will be ready to explore both what has been found and what is missing . Analysis involves breaking the study into parts, understanding each part, assessing the strength of evidence, and drawing conclusions about its relationship to your topic.

Read through the information sources you have selected and try to analyze, understand and critique what you read. Critically review each source's methods, procedures, data validity/reliability, and other themes of interest. Consider how each source approaches your topic in addition to their collective points of intersection and separation . Offer an appraisal of past and current thinking, ideas, policies, and practices, identify gaps within the research, and place your current work and research within this wider discussion by considering how your research supports, contradicts, or departs from other scholars’ research and offer recommendations for future research.

Top 10 Tips for Analyzing the Research

Define key terms
Note key statistics
Determine emphasis, strengths & weaknesses
Critique research methodologies used in the studies
Distinguish between author opinion and actual results
Identify major trends, patterns, categories, relationships, and inconsistencies
Recognize specific aspects in the study that relate to your topic
Disclose any gaps in the literature
Stay focused on your topic
Excluding landmark studies, use current, up-to-date sources

Prepared by the fine librarians at California State University Sacramento.

Synthesis vs Summary

Your literature review should not simply be a summary of the articles, books, and other scholarly writings you find on your topic. It should synthesize the various ideas from your sources with your own observations to create a map of the scholarly conversation taking place about your research topics along with gaps or areas for further research.

Bringing together your review results is called synthesis. Synthesis relies heavily on pattern recognition and relationships or similarities between different phenomena. Recognizing these patterns and relatedness helps you make creative connections between previously unrelated research and identify any gaps.

As you read, you'll encounter various ideas, disagreements, methods, and perspectives which can be hard to organize in a meaningful way. A synthesis matrix also known as a Literature Review Matrix is an effective and efficient method to organize your literature by recording the main points of each source and documenting how sources relate to each other. If you know how to make an Excel spreadsheet, you can create your own synthesis matrix, or use one of the templates below.

Because a literature review is NOT a summary of these different sources, it can be very difficult to keep your research organized. It is especially difficult to organize the information in a way that makes the writing process simpler. One way that seems particularly helpful in organizing literature reviews is the synthesis matrix. Click on the link below for a short tutorial and synthesis matrix spreadsheet.

Literature Review and Synthesis
Lit Review Synthesis Matrix
Synthesis Matrix Example

A literature review must include a thesis statement, which is your perception of the information found in the literature.

A literature review:

Demonstrates your thorough investigation of and acquaintance with sources related to your topic
Is not a simple listing, but a critical discussion
Must compare and contrast opinions
Must relate your study to previous studies
Must show gaps in research
Can focus on a research question or a thesis
Includes a compilation of the primary questions and subject areas involved
Identifies sources

Organizing Your Literature Review

The structure of the review is divided into three main parts—an introduction, body, and the conclusion.

Image result for literature review format

Introduction

Discuss what is already known about your topic and what readers need to know in order to understand your literature review.

Scope, Method, Framework: Explain your selection criteria and similarities between your sources. Be sure to mention any consistent methods, theoretical frameworks, or approaches.
Research Question or Problem Statement: State the problem you are addressing and why it is important. Try to write your research question as a statement.
Thesis : Address the connections between your sources, current state of knowledge in the field, and consistent approaches to your topic.
Format: Describe your literature review’s organization and adhere to it throughout.

Body

The discussion of your research and its importance to the literature should be presented in a logical structure.

Chronological: Structure your discussion by the literature’s publication date moving from the oldest to the newest research. Discuss how your research relates to the literature and highlight any breakthroughs and any gaps in the research.
Historical: Similar to the chronological structure, the historical structure allows for a discussion of concepts or themes and how they have evolved over time.
Thematic: Identify and discuss the different themes present within the research. Make sure that you relate the themes to each other and to your research.
Methodological: This type of structure is used to discuss not so much what is found but how. For example, an methodological approach could provide an analysis of research approaches, data collection or and analysis techniques.

Provide a concise summary of your review and provide suggestions for future research.

Writing the Review

A literature review is a review and synthesis of existing research on a topic or research question. A literature review is meant to analyze the scholarly literature, make connections across writings and identify strengths, weaknesses, trends, and missing conversations. A literature review should address different aspects of a topic as it relates to your research question. A literature review goes beyond a description or summary of the literature you have read.

Understanding Literature Reviews

I. Getting Started with a Workshop Video (Highly recommended!)

Searching for Literature Reviews: Before You Write, You Have to Find https://www.youtube.com/watch?v=9la5ytz9MmM

A lecture by the Writing Center, TAMU.

II. What is a Literature Review?

Generally, the purpose of a review is to analyze critically a segment of a published body of knowledge through summary, classification, and comparison of prior research studies, reviews of literature, and theoretical articles. <http://writing.wisc.edu/Handbook/ReviewofLiterature.html>
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. < http://writingcenter.unc.edu/resources/handouts-demos/specific-writing-assignments/literature-reviews >
A literature review is a body of text that aims to review the critical points of current knowledge including substantive findings as well as theoretical and methodological contributions to a particular topic...Its ultimate goal is to bring the reader up to date with current literature on a topic and forms the basis for another goal, such as future research that may be needed in the area. <http://en.wikipedia.org/wiki/Literature_review>

III. What Major Steps Literature Reviews Require?

1. Develop a review protocol. Protocols define the scope of studies that will be reviewed, the process through which studies will be identified, and the outcomes that will be examined. Protocols also specify the time period during which relevant studies will have been conducted, the outcomes to be examined in the review, and keyword strategies for the literature search. 2. Identify relevant studies, often through a systematic search of the literature. 3. Screen studies for relevance and the adequacy of study design, implementation, and reporting. 4. Retrieve and summarize information on the intervention studied, the study characteristics, and the study findings. 5. Combine findings within studies and across studies when relevant. < http://ies.ed.gov/ncee/wwc/pdf/reference_resources/wwc_procedures_v2_1_standards_handbook.pdf>
The basic stages in a typical research project are: i) identify your topic of interest, ii) perform a literature review, iii) generate related questions, iv) state your unsolved problem or hypothesis, v) find or develop a solution, and vi) document your results.
The four stages required: Problem formulation—which topic or field is being examined and what are its component issues? Literature search—finding materials relevant to the subject being explored Data evaluation—determining which literature makes a significant contribution to the understanding of the topic Analysis and interpretation—discussing the findings and conclusions of pertinent literature < http://library.ucsc.edu/help/howto/write-a-literature-review#components >

IV. What Basic Elements Comprise a Literature Review?

An overview of the subject, issue or theory under consideration, along with the objectives of the literature review
Division of works under review into categories (e.g. those in support of a particular position, those against, and those offering alternative theses entirely)
Explanation of how each work is similar to and how it varies from the others
Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research

< http://library.ucsc.edu/help/howto/write-a-literature-review#components > V. Which Citation Tool Are You Going to Use to Manage the Search Results?

Choose your citation tool before conducing your literature reviews. If you decide to use RefWorks , the information can be found at http://tamu.libguides.com/refworks .

4 Step Guide to Writing a Literature Review

(as transcribed by Clark College Libraries )

1. What is a Literature Review?

A literature review is a description of the literature relevant to a particular field or topic.

It gives an overview of:

what has been said
key writers
prevailing theories and hypotheses
questions being asked
appropriate and useful methods and methodologies

It make take two forms

Purely descriptive - as in an annotated bibliography. A descriptive review should not just list and paraphrase, but should add comment and bring out themes and trends.
A critical assessment of the literature in a particular field, stating where tje weaknesses amd gaps are, contrasting the views of particular authors, or raising questions. It will evaluate and show relationships, so that key themes emerge.
A whole paper, which annotates and/or critiques the literature in a particular subject area.
Part of a thesis or dissertation, forming an early context-setting chapter.
A useful background outlining a piece of research, or putting forward a hypothesis.

DO look at the relationships between the views and draw out themes

DON'T just write a list of quote authors without citing them.

2. The Stages of a Literature Review.

Define the problem.

It is important to define the problem or area which you wish to address.
Have a purpose for your literature review to narrow the scope of what you need to look out for when you read.

Carry out a search for relevant materials.

Peer reviewed journal articles
Newspaper articles
Historical records
Commercial/government reports and statistical information
Theses and dissertations
Other relevant information
Search the university or academic library with a good collection in your subject area.
Search using the internet--but be sure to avoid the pitfalls.
Use specific rather than general keywords and phrases for your search strategy.

Evaluate the materials.

Points to consider when evaluating material:

Author credentials--are they an expert in the field? Are they affiliated to a reputable organization?
Date of publication--is it sufficiently current or has knowledge moved on?
If a book--is it the latest edition?
If a journal--is it a peer reviewed, scholarly journal?
Is the publisher reputable and scholarly?
Is it addressing a scholarly audience?
Does it review relevant literature?
Is it an objective fact-based viewpoint? Is it logically organized and clear to follow?
Does it follow a particular theoretical viewpoint, e.g.feminist?
What is the relationship of this work to other material on the same topic--does it substantiate it or add a different perspective?
If using research, is the design sound? Is it primary or secondary material?
If it is from a practice-based perspective, what are the implications for practice?

Analyse the findings.

What themes emerge, and what conclusions can be drawn?
What are the major similarities and differences between various writers?
Are there any significant questions which emerge and which could form a basis for further investigation?

3. How to Organize a Literature Review

Introduction: Define the topic and state reasons for choice. You could also point out overall trends, gaps and themes that emerge.

Body: Discuss your sources. You can organize your discussion chronologically, thematically or methidologically.

Conclusion: Summarize the major contributions, evaluating the current position, and pointing out flaws in methodology, gaps in the research, contradictions and areas for further study.

You are now at the stage when you can write up your literature review.

4. Further Information.

A literature review is a survey of the scholarly literature published on a given issue, research topic, or theory, and provides a description, summary, and critical evaluation of each work. Rather than providing a new research insight, a literature review lays the groundwork for an in-depth research project analyzing previous research.

Literature Reviews

Steps for Conducting a Lit Review
Finding "The Literature"
Organizing/Writing
Peer Review
Citation/Style Guides

1. Choose a topic. Define your research question.

Your literature review should be guided by a central research question. Remember, it is not a collection of loosely related studies in a field but instead represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

Make sure your research question is not too broad or too narrow. Is it manageable?
Begin writing down terms that are related to your question. These will be useful for searches later.
If you have the opportunity, discuss your topic with your professor.

2. Decide on the scope of your review.

How many studies do you need to look at? How comprehensive should it be? How many years should it cover?

Tip: This may depend on your assignment. How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. You can use a Discovery Service , such as and individual database.

Tips:

Look at the library's research guides in your discipline to select discipline-specific databases. Don't forget to look at books!
Make an appointment with or contact your librarian to make sure you aren't missing major databases.

4. Conduct your searches and find the literature. Keep track of your searches!

Review the abstracts of research studies carefully. This will save you time.
Write down the searches you conduct in each database so that you may duplicate them if you need to later (or avoid dead-end searches that you'd forgotten you'd already tried).
Save your searches and results by creating an account and signing in.
Use the bibliographies and references of research studies you find to locate others.
Ask your professor or a scholar in the field if you are missing any key works in the field.
Keep track of your searches by using Zotero or another bibliographic tool.

5. Review the literature.

Some questions to help you analyze the research:

What was the research question of the study you are reviewing? What were the authors trying to discover?
Was the research funded by a source that could influence the findings?
What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions. Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
If there are conflicting studies, why do you think that is?
How are the authors viewed in the field? Has this study been cited?; if so, how has it been analyzed?
Again, review the abstracts carefully.
Keep careful notes so that you may track your thought processes during the research process.

Conducting a literature review is usually recursive, meaning that somewhere along the way, you'll find yourself repeating steps out-of-order.

That is actually a good sign.

Reviewing the research should lead to more research questions and those questions will likely lead you to either revise your initial research question or go back and find more literature related to a more specific aspect of your research question.

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field.

A literature review should:

Provide a comprehensive and updated review of the literature;
Explain why this review has taken place;
Articulate a position or hypothesis;
Acknowledge and account for conflicting and corroborating points of view

From S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

Demonstrate how a study fills a gap in research
Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

Organizes or describes a topic
Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
It may be too focused. Some niche studies may miss the bigger picture.
It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

Introduction to Research Process: Literature Review Steps

When seeking information for a literature review or for any purpose, it helps to understand information-seeking as a process that you can follow. 5 Each of the six (6) steps has its own section in this web page with more detail. Do (and re-do) the following six steps:

1. Define your topic. The first step is defining your task -- choosing a topic and noting the questions you have about the topic. This will provide a focus that guides your strategy in step II and will provide potential words to use in searches in step III.

2. Develop a strategy. Strategy involves figuring out where the information might be and identifying the best tools for finding those types of sources. The strategy section identifies specific types of research databases to use for specific purposes.

3. Locate the information . In this step, you implement the strategy developed in II in order to actually locate specific articles, books, technical reports, etc.

4. Use and Evaluate the information. Having located relevant and useful material, in step IV you read and analyze the items to determine whether they have value for your project and credibility as sources.

5. Synthesize. In step V, you will make sense of what you've learned and demonstrate your knowledge. You will thoroughly understand, organize and integrate the information --become knowledgeable-- so that you are able to use your own words to support and explain your research project and its relationship to existing research by others.

6. Evaluate your work. At every step along the way, you should evaluate your work. However, this final step is a last check to make sure your work is complete and of high quality.

Continue below to begin working through the process.

5. Eisenberg, M. B., & Berkowitz, R. E. (1990). Information Problem-Solving: the Big Six Skills Approach to Library & Information Skills Instruction . Norwood, NJ: Ablex Publishing.

1. Define your topic.

I. Define your topic

A. Many students have difficulty selecting a topic. You want to find a topic you find interesting and will enjoy learning more about.

B. Students often select a topic that is too broad. You may have a broad topic in mind initially and will need to narrow it.

1. To help narrow a broad topic :

a. Brainstorm.

1). Try this technique for brainstorming to narrow your focus.

a) Step 1. Write down your broad topic.

b) Step 2. Write down a "specific kind" or "specific aspect" of the topic you identified in step 1.

c) Step 3. Write down an aspect --such as an attribute or behavior-- of the "specific kind" you identified in step 2.

d) Step 4. Continue to add levels of specificity as needed to get to a focus that is manageable. However, you may want to begin researching the literature before narrowing further to give yourself the opportunity to explore what others are doing and how that might impact the direction that you take for your own research.

2) Three examples of using the narrowing technique. These examples start with very, very broad topics, so the topic at step 3 or 4 in these examples would be used for a preliminary search in the literature in order to identify a more specific focus. Greater specificity than level 3 or 4 will ultimately be necessary for developing a specific research question. And we may discover in our preliminary research that we need to alter the direction that we originally were taking.

a) Example 1.

Step 1. information security

Step 2. protocols

Step 3. handshake protocol

Brainstorming has brought us to focus on the handshake protocol.

b) Example 2.

Step 1. information security

Step 2. single sign-on authentication

Step 3. analyzing

Step 4. methods

Brainstorming has brought us to focus on methods for analyzing the security of single sign-on authentication

c) Example 3. The diagram below is an example using the broad topic of "software" to show two potential ways to begin to narrow the topic.

C. Once you have completed the brainstorming process and your topic is more focused, you can do preliminary research to help you identify a specific research question .

1) Examine overview sources such as subject-specific encyclopedias and textbooks that are likely to break down your specific topic into sub-topics and to highlight core issues that could serve as possible research questions. [See section II. below on developing a strategy to learn how to find these encyclopedias]

2). Search the broad topic in a research database that includes scholarly journals and professional magazines (to find technical and scholarly articles) and scan recent article titles for ideas. [See section II. below on developing a strategy to learn how to find trade and scholarly journal articles]

D. Once you have identified a research question or questions, ask yourself what you need to know to answer the questions. For example,

1. What new knowledge do I need to gain?

2. What has already been answered by prior research of other scholars?

E. Use the answers to the questions in C. to identify what words to use to describe the topic when you are doing searches.

1. Identify key words

a. For example , if you are investigating "security audits in banking", key terms to combine in your searches would be: security, audits, banking.

2. Create a list of alternative ways of referring to a key word or phrase

a.For example , "information assurance" may be referred to in various ways such as: "information assurance," "information security," and "computer security."

b. Use these alternatives when doing searches.

3. As you are searching, pay attention to how others are writing about the topic and add new words or phrases to your searches if appropriate.

2. Develop a strategy.

II. Develop a strategy for finding the information.

A. Start by considering what types of source might contain the information you need . Do you need a dictionary for definitions? a directory for an address? the history of a concept or technique that might be in a book or specialized encyclopedia? today's tech news in an online tech magazine or newspaper? current research in a journal article? background information that might be in a specialized encyclopedia? data or statistics from a specific organization or website? Note that you will typically have online access to these source types.

B. This section provides a description of some of the common types of information needed for research.

1. For technical and business analysis , look for articles in technical and trade magazines . These articles are written by information technology professionals to help other IT professionals do their jobs better. Content might include news on new developments in hardware or software, techniques, tools, and practical advice. Technical journals are also likely to have product ads relevant to information technology workers and to have job ads. Examples iof technical magazines include Network Computing and IEEE Spectrum .

2. To read original research studies , look for articles in scholarly journals and conference proceedings . They will provide articles written by information technology professionals who are reporting original research; that is, research that has been done by the authors and is being reported for the first time. The audience for original research articles is other information technology scholars and professionals. Examples of scholarly journals include Journal of Applied Security Research , Journal of Management Information Systems , IEEE Transactions on Computers , and ACM Transactions on Information and System Security .

3. For original research being reported to funding agencies , look for technical reports on agency websites. Technical reports are researcher reports to funding agencies about progress on or completion of research funded by the agency.

4. For in-depth, comprehensive information on a topic , look for book-length volumes . All chapters in the book might be written by the same author(s) or might be a collection of separate papers written by different authors.

5. To learn about an unfamiliar topic , use textbooks , specialized encyclopedias and handbooks to get get overviews of topics, history/background, and key issues explained.

6. For instructions for hardware, software, networking, etc., look for manuals that provide step-by-step instructions.

7. For technical details about inventions (devices, instruments, machines), look for patent documents .

C. NOTE - In order to search for and find original research studies, it will help if you understand how information is produced, packaged and communicated within your profession. This is explained in the tab "Research Communication: Graphic."

3. Locate the information.

III. Locate the information

A. Use search tools designed to find the sources you want. Types of sources were described in section II. above.

Always feel free to Ask a librarian for assistance when you have questions about where and how locate the information you need.

B. Evaluate the search results (no matter where you find the information)

1. Evaluate the items you find using at least these 5 criteria:

a. accuracy -- is the information reliable and error free?

1) Is there an editor or someone who verifies/checks the information?

2) Is there adequate documentation: bibliography, footnotes, credits?

3) Are the conclusions justified by the information presented?

b. authority -- is the source of the information reputable?

1) How did you find the source of information: an index to edited/peer-reviewed material, in a bibliography from a published article, etc.?

2) What type of source is it: sensationalistic, popular, scholarly?

c. objectivity -- does the information show bias?

1) What is the purpose of the information: to inform, persuade, explain, sway opinion, advertise?

2) Does the source show political or cultural biases?

d. currency -- is the information current? does it cover the time period you need?

e. coverage -- does it provide the evidence or information you need?

2. Is the search producing the material you need? -- the right content? the right quality? right time period? right geographical location? etc. If not, are you using

a. the right sources?

b. the right tools to get to the sources?

c. are you using the right words to describe the topic?

3. Have you discovered additional terms that should be searched? If so, search those terms.

4. Have you discovered additional questions you need to answer? If so, return to section A above to begin to answer new questions.

4. Use and evaluate the information.

IV. Use the information.

A. Read, hear or view the source

1. Evaluate: Does the material answer your question(s)? -- right content? If not, return to B.

2. Evaluate: Is the material appropriate? -- right quality? If not, return to B.

B. Extract the information from the source : copy/download information, take notes, record citation, keep track of items using a citation manager.

1. Note taking (these steps will help you when you begin to write your thesis and/or document your project.):

a. Write the keywords you use in your searches to avoid duplicating previous searches if you return to search a research database again. Keeping track of keywords used will also save you time if your search is interrupted or you need return and do the search again for some other reason. It will help you remember which search terms worked successfully in which databases

b. Write the citations or record the information needed to cite each article/document you plan to read and use, or make sure that any saved a copy of the article includes all the information needed to cite it. Some article pdf files may not include all of the information needed to cite, and it's a waste of your valuable time to have to go back to search and find the items again in order to be able to cite them. Using citation management software such as EndNote will help keep track of citations and help create bibliographies for your research papers.

c. Write a summary of each article you read and/or why you want to use it.

5. Synthesize.

V. Synthesize.

A. Organize and integrate information from multiple sources

B. Present the information (create report, speech, etc. that communicates)

C. Cite material using the style required by your professor or by the venue (conference, publication, etc.). For help with citation styles, see Guide to Citing Sources . A link to the citing guide is also available in the "Get Help" section on the left side of the Library home page

6. Evaluate your work.

VI. Evaluate the paper, speech, or whatever you are using to communicate your research.

A. Is it effective?

B. Does it meet the requirements?

C. Ask another student or colleague to provide constructive criticism of your paper/project.

What is a Literature Review?

Description.

A literature review, also called a review article or review of literature, surveys the existing research on a topic. The term "literature" in this context refers to published research or scholarship in a particular discipline, rather than "fiction" (like American Literature) or an individual work of literature. In general, literature reviews are most common in the sciences and social sciences.

Literature reviews may be written as standalone works, or as part of a scholarly article or research paper. In either case, the purpose of the review is to summarize and synthesize the key scholarly work that has already been done on the topic at hand. The literature review may also include some analysis and interpretation. A literature review is not a summary of every piece of scholarly research on a topic.

Why are literature reviews useful?

Literature reviews can be very helpful for newer researchers or those unfamiliar with a field by synthesizing the existing research on a given topic, providing the reader with connections and relationships among previous scholarship. Reviews can also be useful to veteran researchers by identifying potentials gaps in the research or steering future research questions toward unexplored areas. If a literature review is part of a scholarly article, it should include an explanation of how the current article adds to the conversation. (From: https://library.drake.edu/englit/criticism)

How is a literature review different from a research article?

Research articles: "are empirical articles that describe one or several related studies on a specific, quantitative, testable research question....they are typically organized into four text sections: Introduction, Methods, Results, Discussion." Source: https://psych.uw.edu/storage/writing_center/litrev.pdf)

Steps for Writing a Literature Review

1. Identify and define the topic that you will be reviewing.

The topic, which is commonly a research question (or problem) of some kind, needs to be identified and defined as clearly as possible. You need to have an idea of what you will be reviewing in order to effectively search for references and to write a coherent summary of the research on it. At this stage it can be helpful to write down a description of the research question, area, or topic that you will be reviewing, as well as to identify any keywords that you will be using to search for relevant research.

2. Conduct a Literature Search

Use a range of keywords to search databases such as PsycINFO and any others that may contain relevant articles. You should focus on peer-reviewed, scholarly articles . In SuperSearch and most databases, you may find it helpful to select the Advanced Search mode and include "literature review" or "review of the literature" in addition to your other search terms. Published books may also be helpful, but keep in mind that peer-reviewed articles are widely considered to be the “gold standard” of scientific research. Read through titles and abstracts, select and obtain articles (that is, download, copy, or print them out), and save your searches as needed. Most of the databases you will need are linked to from the Cowles Library Psychology Research guide .

3. Read through the research that you have found and take notes.

Absorb as much information as you can. Read through the articles and books that you have found, and as you do, take notes. The notes should include anything that will be helpful in advancing your own thinking about the topic and in helping you write the literature review (such as key points, ideas, or even page numbers that index key information). Some references may turn out to be more helpful than others; you may notice patterns or striking contrasts between different sources; and some sources may refer to yet other sources of potential interest. This is often the most time-consuming part of the review process. However, it is also where you get to learn about the topic in great detail. You may want to use a Citation Manager to help you keep track of the citations you have found.

4. Organize your notes and thoughts; create an outline.

At this stage, you are close to writing the review itself. However, it is often helpful to first reflect on all the reading that you have done. What patterns stand out? Do the different sources converge on a consensus? Or not? What unresolved questions still remain? You should look over your notes (it may also be helpful to reorganize them), and as you do, to think about how you will present this research in your literature review. Are you going to summarize or critically evaluate? Are you going to use a chronological or other type of organizational structure? It can also be helpful to create an outline of how your literature review will be structured.

5. Write the literature review itself and edit and revise as needed.

The final stage involves writing. When writing, keep in mind that literature reviews are generally characterized by a summary style in which prior research is described sufficiently to explain critical findings but does not include a high level of detail (if readers want to learn about all the specific details of a study, then they can look up the references that you cite and read the original articles themselves). However, the degree of emphasis that is given to individual studies may vary (more or less detail may be warranted depending on how critical or unique a given study was). After you have written a first draft, you should read it carefully and then edit and revise as needed. You may need to repeat this process more than once. It may be helpful to have another person read through your draft(s) and provide feedback.

6. Incorporate the literature review into your research paper draft. (note: this step is only if you are using the literature review to write a research paper. Many times the literature review is an end unto itself).

After the literature review is complete, you should incorporate it into your research paper (if you are writing the review as one component of a larger paper). Depending on the stage at which your paper is at, this may involve merging your literature review into a partially complete Introduction section, writing the rest of the paper around the literature review, or other processes.
