What is a Literature Review?

A literature review is a critical summary and evaluation of the existing research (e.g., academic journal articles and books) on a specific topic. It is typically included as a separate section or chapter of a research paper or dissertation, serving as a contextual framework for a study. Literature reviews can vary in length depending on the subject and nature of the study, with most being about equal length to other sections or chapters included in the paper. Essentially, the literature review highlights previous studies in the context of your research and summarizes your insights in a structured, organized format. Next, let’s look at the overall purpose of a literature review.

Literature reviews are considered an integral part of research across most academic subjects and fields. The primary purpose of a literature review in your study is to:

Provide a Foundation for Current Research

Since the literature review provides a comprehensive evaluation of the existing research, it serves as a solid foundation for your current study. It’s a way to contextualize your work and show how your research fits into the broader landscape of your specific area of study.  

Define Key Concepts and Theories

The literature review highlights the central theories and concepts that have arisen from previous research on your chosen topic. It gives your readers a more thorough understanding of the background of your study and why your research is particularly significant .

Demonstrate Critical Evaluation 

A comprehensive literature review shows your ability to critically analyze and evaluate a broad range of source material. And since you’re considering and acknowledging the contribution of key scholars alongside your own, it establishes your own credibility and knowledge.

Show How Research and Methodologies Have Evolved

Another purpose of literature reviews is to provide a historical perspective and demonstrate how research and methodologies have changed over time, especially as data collection methods and technology have advanced. And studying past methodologies allows you, as the researcher, to understand what did and did not work and apply that knowledge to your own research.  

Identify Gaps in Existing Research

Besides discussing current research and methodologies, the literature review should also address areas that are lacking in the existing literature. This helps further demonstrate the relevance of your own research by explaining why your study is necessary to fill the gaps.

Support Your Argument

A good literature review should provide evidence that supports your research questions and hypothesis. For example, your study may show that your research supports existing theories or builds on them in some way. Referencing previous related studies shows your work is grounded in established research and will ultimately be a contribution to the field.

Writing a Literature Review

Welcome to the Purdue OWL

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

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

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

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

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

What are the parts of a lit review?

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

Introduction:

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

Conclusion:

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

How should I organize my lit review?

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

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

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

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

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

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

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

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

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.

How does a literature review help establish the research gap in a particular field

A literature review plays a crucial role in identifying and establishing the research gap in a particular field through the following mechanisms;

• Summarizing Existing Knowledge:  The literature review provides a comprehensive summary of existing research on a given topic, allowing researchers to understand the current state of knowledge in the field.
• Identifying Patterns and Trends:  By reviewing multiple studies, a literature review helps researchers identify patterns, trends, and common themes in the existing literature. This analysis highlights areas where research has been concentrated and areas where it may be lacking.
• Highlighting Consensus and Controversies:  The literature review reveals areas where there is a consensus among researchers and areas where there are conflicting findings or ongoing debates. This can point to gaps in understanding that require further investigation.
• Pointing to Unanswered Questions:  As researchers analyze the literature, they may come across questions that have not been adequately addressed or answered by existing studies. These unanswered questions signify potential research gaps.
• Examining Methodological Limitations:  A thorough literature review involves evaluating the methodologies employed in previous studies. Identifying limitations or gaps in methodology can suggest areas where further research is needed to address these shortcomings.
• Assessing Currency of Information:  If there is a lack of recent studies on a specific aspect of a topic, it may indicate that there is a gap in recent research that needs attention.
• Considering Emerging Trends:  The literature review allows researchers to identify emerging trends or new developments in the field. These trends may open up avenues for novel research directions.
• Evaluating Geographical or Cultural Gaps:  Geographical or cultural gaps in the literature can also indicate areas where further research is needed to provide a more comprehensive understanding of the topic.
• Analyzing Changes Over Time:  A temporal analysis of the literature can reveal how research on a particular topic has evolved. Recognizing changes and shifts in focus over time may uncover gaps in understanding that need addressing.
• Seeking Gaps in Application:  Researchers can identify gaps in the application of theoretical frameworks or interventions within practical settings. This may suggest opportunities for applied research.

By systematically examining the existing literature and critically evaluating its content, methodologies, and findings, researchers can pinpoint areas where knowledge is incomplete or where further investigation is necessary. Identifying these gaps helps shape the rationale for the new study and positions it within the broader context of the existing body of knowledge.

In what ways does a literature review assist in framing research questions and hypotheses

A literature review assists in framing research questions and hypotheses in several ways;

• Identification of Existing Knowledge:  A literature review provides an overview of existing knowledge on a particular topic, helping researchers understand what has already been studied and established in the field.
• Identification of Gaps:  By analyzing the existing literature, researchers can identify gaps, limitations, or unanswered questions. These gaps serve as a basis for formulating research questions, as they highlight areas where new knowledge is needed.
• Understanding Theoretical Foundations:  The literature review helps researchers understand the theoretical frameworks and concepts that have been used in previous studies. This understanding guides the formulation of research questions that align with established theories or challenge existing paradigms.
• Inspiration from Previous Research:  Reviewing the literature provides researchers with insights and inspiration from previous studies. It helps them identify interesting phenomena, patterns, or trends that can lead to the formulation of relevant and meaningful research questions.
• Identification of Variables:  Researchers can identify key variables, factors, or elements that have been studied in the literature. This identification informs the formulation of hypotheses and guides the operationalization of variables in the research design.
• Clarity in Focus:  A literature review helps researchers narrow down the scope of their study by clarifying the focus and defining the specific aspects of the topic that need further investigation. This clarity contributes to the formulation of precise and focused research questions.
• Understanding Methodologies:  By examining the methodologies used in previous studies, researchers gain insights into various research approaches. This understanding guides the selection of an appropriate research methodology for their own study, influencing the formulation of research questions.
• Building on Previous Findings:  Researchers may build on or extend previous findings identified in the literature. Formulating research questions in the context of existing research allows for the advancement of knowledge and contributes to the ongoing scholarly conversation.
• Alignment with Research Goals:  The literature review helps researchers align their research questions with the overarching goals and objectives of the study. This ensures that the research questions are relevant and contribute meaningfully to the field.
• Contextualizing Hypotheses:  Based on the insights gained from the literature review, researchers can formulate hypotheses that are grounded in existing theories or empirical evidence. This contextualization strengthens the rationale for the hypotheses.

A well-conducted literature review informs and guides the process of formulating research questions and hypotheses by providing a foundation of knowledge, highlighting gaps, and offering insights from previous studies. This ensures that the research questions are relevant, theoretically grounded, and contribute to the advancement of the field.

Can a well-conducted literature review enhance the credibility of academic research

Yes! A well-conducted literature review is  essential  for enhancing the credibility of academic research in several ways;

1. Demonstrates Expertise:  A comprehensive review shows you have a deep understanding of the existing knowledge and relevant theory in your field. This establishes you as an authority and positions your research within the broader context.

By investing time and effort in conducting a well-structured and insightful literature review, you’ll lay a solid foundation for your research and significantly enhance its credibility and potential impact.

How does the literature review process aid in identifying key theories and concepts relevant to the research topic

The literature review process plays a crucial role in identifying key theories and concepts relevant to your research topic in several ways;

1. Exposure to Existing Knowledge:  As you dive into relevant scholarly articles, books, and other sources, you’ll be exposed to the prevailing theories and concepts surrounding your topic. This initial immersion provides a broad understanding of the landscape and potential key players.

2. Identifying Recurring Themes and Ideas:  As you analyze and synthesize the collected information, you’ll start noticing recurring themes, terminologies, and arguments. These recurrent elements likely represent the key theories and concepts shaping the field.

3. Recognizing Debates and Contradictions:  A good literature review doesn’t shy away from presenting opposing viewpoints and ongoing debates. Recognizing these tensions and contradictions can highlight unresolved questions or emerging concepts, guiding your own research focus.

4. Evaluating Strengths and Weaknesses of Existing Theories:  Critically analyzing past research allows you to identify the strengths and limitations of existing theories. This helps you understand which theories are robust and applicable and which areas need further exploration, potentially leading to innovative approaches.

5. Building Upon Previous Work:  The literature review allows you to see how different theories and concepts relate to each other and your research question. This knowledge helps you position your work within the existing conversation, building upon established ideas or introducing new ones.

Additional Tips

• Keyword Exploration:  Utilize relevant keywords in your search queries to discover important theories and concepts associated with your topic.
• Author Tracking:  Pay attention to frequently cited authors and influential figures in your field. Their work often reflects key theories and concepts.
• Consult Experts:  Engage with professors, researchers, or librarians specializing in your field. They can provide guidance on prominent theories and suggest relevant sources.
• Conceptual Mapping:  Visualize the relationships between concepts and theories you encounter through mind maps or diagrams. This aids in identifying key players and their connections.

What challenges might researchers face when conducting a literature review, and how can these be addressed

Conducting a robust literature review can be an enriching, yet challenging, experience for researchers. Here are some common hurdles and tips on how to overcome them:

1. Information Overload:  With the vast amount of published research available, it can be overwhelming to identify, select, and manage relevant sources.

• Develop a focused research question:  This helps refine your search terms and target specific areas within the broader field.
• Utilize advanced search techniques:  Boolean operators, filters, and keyword variations can improve the precision of your search results.
• Leverage reference management tools:  Software like Mendeley or Zotero help organize and annotate your findings efficiently.

2. Bias and Incomplete Coverage:  Your search strategy and chosen sources might unintentionally introduce bias towards particular viewpoints or neglect relevant areas.

• Consult with librarians or research experts:  They can offer guidance on diverse perspectives and alternative databases beyond the typical search engines.
• Seek out dissenting voices and alternative methodologies:  Consider including research that challenges your initial assumptions to ensure a balanced review.
• Be transparent about limitations:  Acknowledge potential biases and acknowledge areas where your review might be incomplete.

3. Difficulty Analyzing and Synthesizing Information:  Turning information into meaningful insights can be challenging, especially when dealing with conflicting studies or complex concepts.

• Develop a clear analytical framework:  This helps you categorize and evaluate studies based on specific criteria like methodology, theoretical perspectives, and findings.
• Identify key themes and arguments:  Look for recurring patterns and contrasting viewpoints across different studies.
• Use critical thinking skills:  Evaluate the strengths, weaknesses, and potential limitations of each study and its contribution to your understanding.

4. Time Constraints:  Conducting a thorough literature review can be time-consuming, especially for students or researchers with limited resources.

• Develop a realistic timeline:  Break down the review process into manageable steps and allocate sufficient time for each stage.
• Prioritize sources strategically:  Focus on highly relevant and impactful studies initially, then expand your search as needed.
• Seek support from peers or mentors:  Discuss your progress and challenges with others to stay motivated and receive feedback.

5. Access to Resources:  Paywalled journals and limited library access can pose a barrier for some researchers, particularly those affiliated with smaller institutions.

• Explore open access resources:  Numerous online platforms offer free access to scholarly articles and books.
• Utilize interlibrary loan services:  Libraries can often borrow materials from other institutions for you.

What is a Literature Review?

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).

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
