Process of Literature Review

This guide was created to help FSU students in the arts and humanities with writing a literature review.

Whether you are writing a literature review for your term paper, research article, or thesis/dissertation, we hope you will find some helpful tips for completing the task.

Each tab in this guide was designed to correspond to each stage of the literature review process. However, research and writing are iterative processes; they do not necessarily follow a linear process. You may find yourself cycling through stages more than once, perhaps going back to your topic after a first reading of articles and books you have discovered. The outline here is meant only as a guide for thinking about the process.

What is a Literature Review?

A Literature Review IS.. .

• a selective, integrated analysis and synthesis of what has been researched and published on a particular topic
• a process, typically starting from selecting a topic to review and concluding with writing a manuscript to report the published works on the topic
• an iterative process: you may have to keep coming back to previous stage(s) to refine your topic, modify the search statements, and/or revise a working thesis, etc.

A Good Literature Review IS NOT...

• a mere summary of what you have read on a topic
• a summary of everything that is reported on a topic
• an annotated bibliography 

         ...BUT IS

• a critical summary of relevant and selective literature on the topic
• written in clear language
• a piece of research on its own

         ...AND DOES

• situate and focus your research in context
• use credible and most relevant sources
• add value to the existing knowledge on the topic

FSU Reading Writing Center

The Florida State University Reading-Writing Center and Digital Studio offers writing support to all FSU students across all the disciplines.

Definitions.

Literature reviews integrate and synthesize previous literature in order to provide a new perspective on a topic.  The review describes, summarizes, evaluates, clarifies, and/or integrates the content.

• A literature review is NOT an annotated bibliography, but an annotated bibliography can serve as the foundation of a literature review by analyzing the individual sources that will become part of the review.
• Literature reviews can also be referred to as annual reviews, research reviews, integrative reviews, research synthesis, and so forth.  Systematic reviews and meta analysis are specific types of literature reviews.

Literatures reviews can be:

a.  Part of a larger study, which provides a foundation and demonstrates understanding of the academic conversation about the topic.

b.  Freestanding, an overview of a topic which is of value because it indicates future areas of study (points out gaps, highlights central or unresolved issues, bridges related or disparate areas, and offers new perspectives) and identifies key authors and texts.

Characteristics of Literature Review

a.  Focus

b.  Goal

c.  Perspective

d. Coverage

e. Organization

f.  Audience

Writing a Literature Review

Welcome to the Purdue OWL

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

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

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

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

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

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

What are the parts of a lit review?

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

Introduction:

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

Conclusion:

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

How should I organize my lit review?

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

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

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

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

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

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

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

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

Writing a literature review.

This handout is available for download in  DOCX format  and  PDF format .

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, as it discusses the research (also called scholarship or literature) in a given field.

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

Different situations and disciplines each have different expectations for literature reviews. In the humanities, authors might include more overt argumentation and interpretation of source material, while in the sciences, authors are more likely to report study designs and results. Always get feedback from those knowledgeable in your field to be sure you understand your discipline’s conventions for literature reviews.

A literature review can be a part of a research paper or scholarly article, usually coming just after the introduction. Such lit reviews only need to cover scholarship important to your topic, though it may also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as class assignments or as publications. In a class, a lit review may help students familiarize themselves with a topic and its important scholars, find gaps in existing research, and/or develop frameworks and methodologies for later research. As a publication, a lit review can help other scholars—especially students and scholars entering a new research area—by collecting, summarizing, synthesizing, and analyzing existing research on a topic.

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 separate place to discuss your goals, research methods, and conclusions.

Introduction:

• An introductory paragraph that explains your working topic and thesis
• 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 common in published, standalone literature reviews)
• 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 structures depending on your goals. Here are just four examples:

Chronological

The simplest approach is to trace the topic’s development over time, which helps familiarize the audience with it. 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 field, and if appropriate in your discipline, give your interpretation of how and why certain developments occurred.

If you have found recurring 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 religious attitudes towards women.

Methodological

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

• 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 theoretical concepts to create a framework for your research.

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

• Research thoroughly and choose your sources wisely; your lit review is only as good as the research it discusses!
• Create an annotated bibliography (see our Annotated Bibliographies handout ) as you research. The information in it will become a foundation for your lit review, while creating it will also help you develop a sense for the larger scholarly conversations in the field.
• Synthesize research rather than just summarizing it. This often means using multiple authors in each paragraph.
• Frame your lit review as an argument if possible and appropriate in your discipline. This will offer you a chance to position yourself in relation to other scholars, to define your intellectual lineage, and to argue for your place in the scholarly conversation.

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

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

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.

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.

Correct my document today

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.

Prevent plagiarism, run a free check.

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.

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.

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 .

A literature review surveys prior research published in 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 used in researching a particular topic and to demonstrate to your readers how your research fits within existing scholarship about the topic.

Importance of a Good Literature Review

A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . 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 in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:

• Give a new interpretation of old material or combine new with old interpretations,
• Trace the intellectual progression of the field, including major debates,
• Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
• Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.

Given this, the purpose of a literature review is to:

• Place each work in the context of its contribution to understanding the research problem being studied.
• Describe the relationship of each work to the others under consideration.
• Identify new ways to interpret prior research.
• Reveal any gaps that exist in the literature.
• Resolve conflicts amongst seemingly contradictory previous studies.
• Identify areas of prior scholarship to prevent duplication of effort.
• Point the way in fulfilling a need for additional research.
• Locate your own research within the context of existing literature [very important].

Types of Literature Reviews

It is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally among scholars that become part of the body of epistemological traditions within the field.

In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.

Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].

Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.

Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena 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 to identify the likely directions for future research.

Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.

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 to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem . Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.

Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

NOTE : Most often the literature review will incorporate some combination of types. For example, a review that examines literature supporting or refuting an argument, assumption, or philosophical problem related to the research problem will also need to include writing supported by sources that establish the history of these arguments in the literature.

Structure and Writing Style

I.  Thinking About Your Literature Review

The structure of a literature review should include the following in support of understanding the research problem :

• An overview of the subject, issue, or theory under consideration, along with the objectives of the literature review,
• Division of works under review into themes or categories [e.g. works that support a particular position, those against, and those offering alternative approaches entirely],
• An 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.

The critical evaluation of each work should consider :

• Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?
• Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?
• Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
• Persuasiveness -- which of the author's theses are most convincing or least convincing?
• Validity -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?

II.  Development of the Literature Review

Four Basic Stages of Writing 1.  Problem formulation -- which topic or field is being examined and what are its component issues? 2.  Literature search -- finding materials relevant to the subject being explored. 3.  Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4.  Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.

Consider the following issues before writing the literature review: Clarify If your assignment is not specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1.  Roughly how many sources would be appropriate to include? 2.  What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3.  Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4.  Should I evaluate the sources in any way beyond evaluating how they relate to understanding the research problem? 5.  Should I provide subheadings and other background information, such as definitions and/or a history? Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read, such as required readings in the course syllabus, are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make the act of reviewing easier if you first limit scope of the research problem. A good strategy is to begin by searching the USC Libraries Catalog for recent books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.

III.  Ways to Organize Your Literature Review

Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] A thematic literature review is the most common approach to summarizing prior research in the social and behavioral sciences. Thematic reviews are organized around a topic or issue, rather than the progression of time, although the progression of time may still be incorporated into a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it would still be organized chronologically reflecting technological developments in media. The difference in this example between a "chronological" and a "thematic" approach is what is emphasized the most: themes related to the role of the Internet in presidential politics. Note that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point being made. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.

Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. However, only include what is necessary for the reader to locate your study within the larger scholarship about the research problem.

Here are examples of other sections, usually in the form of a single paragraph, you may need to include depending on the type of review you write:

• Current Situation : Information necessary to understand the current topic or focus of the literature review.
• Sources Used : Describes the methods and resources [e.g., databases] you used to identify the literature you reviewed.
• History : The chronological progression of the field, the research literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
• Selection Methods : Criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed [i.e., scholarly] sources.
• Standards : Description of the way in which you present your information.
• Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?

IV.  Writing Your Literature Review

Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.

Use Evidence A literature review section is, in this sense, just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information, but that are not key to understanding the research problem, can be included in a list of further readings . Use Quotes Sparingly Some short quotes are appropriate if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, is not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute for using your own words in reviewing the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work and the work of others. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.

V.  Common Mistakes to Avoid

These are the most common mistakes made in reviewing social science research literature.

• Sources in your literature review do not clearly relate to the research problem;
• You do not take sufficient time to define and identify the most relevant sources to use in the literature review related to the research problem;
• Relies exclusively on secondary analytical sources rather than including relevant primary research studies or data;
• Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
• Does not describe the search procedures that were used in identifying the literature to review;
• Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
• Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Writing Tip

Break Out of Your Disciplinary Box!

Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.

Frodeman, Robert. The Oxford Handbook of Interdisciplinarity . New York: Oxford University Press, 2010.

Another Writing Tip

Don't Just Review for Content!

While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:

• How are they organizing their ideas?
• What methods have they used to study the problem?
• What theories have been used to explain, predict, or understand their research problem?
• What sources have they cited to support their conclusions?
• How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?

When you begin to write your literature review section, you'll be glad you dug deeper into how the research was designed and constructed because it establishes a means for developing more substantial analysis and interpretation of the research problem.

Hart, Chris. Doing a Literature Review: Releasing the Social Science Research Imagination . Thousand Oaks, CA: Sage Publications, 1 998.

Yet Another Writing Tip

When Do I Know I Can Stop Looking and Move On?

Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:

• Look for repeating patterns in the research findings . If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research?  Does it forge a new path? Or, does is merely add more of the same thing being said?
• Look at sources the authors cite to in their work . If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been generated to address the research problem.
• Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review [see next sub-tab]. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. Here again, if the same authors are being cited again and again, this may indicate no new literature has been written on the topic.

What is a literature review, and why do one?

Literature reviews summarize the existing conversation on a topic. They can accomplish something similar to environmental scans, researching industry best practices, summarizing evidence-based approaches, or laying the groundwork for a new initiative. A literature review can be done as its own complete product, or it can serve as an introduction for the original research you plan to do to add to the conversation in your field. In academic research contexts, such as for theses and dissertations, they provide a grounding for the new work a scholar is presenting to add to this conversation. 

However, most guidance available on conducting literature reviews does not consider how to do a literature review in a nonprofit context, or outside of university settings in general.

What a literature review could do for you

Outside of academia, your motivations for research may be different. For a non-profit, literature reviews might help you:

• Gather evidence to assess your organization’s best practices
• Provide evidence for grant proposals
• Look for new approaches to an issue
• Provide background or a methodology for your original research
• Synthesize what’s known on a topic, to share with others working in your area
• Find out if someone has already studied the topic you are interested in

What are the steps?

What you're looking to create may not be exactly a formal literature review. Most guidance on conducting literature reviews assumes an academic context, with strict guidelines for how a review should be conducted. As a non-profit or NGO worker your resources, needs, and audience may be different from researchers in academic institutions.

Here is a structure to follow based on the literature review process, with questions to consider along the way to help you tailor the process to your context. Each step is described in greater detail below the infographic.

 The process doesn't have to be linear! You can return to each step as needed throughout your research.

 Preparation

Think through your needs, capacity, and resources to plan your work.

What is your motivation for creating a review on your topic?

Do any literature reviews exist on this topic already?

• Do you have fellow staff or volunteers that could contribute to this project?
• How much time do you (and others) have to dedicate?
• Do any staff or volunteers have relevant experience to contribute?

Information and supports:

• You may have more resources available to you than you realize.
• See "Where to search" in the "Retrieval" section for more ideas.

Keeping track of sources:

• To keep track of the sources you intend to use, you can keep a list in your own document, or you may want to consider using citation management software.
• Citation managers are designed to make it quick and easy to track and cite your sources. You can read more at  Citation management software and tools .

Keeping track of the information you're collecting:

• What kind of note-taking works well for you?
• Even if something feels memorable in the moment, it can be difficult to remember where you found a piece of information even the next day.
• Many citation management tools allow you to add notes or attach documents.

Consider any possible search terms that relate to your topic -- it's useful to try different combinations of words to see what results you get back. Your early searches may help you find relevant terms to add to your list.

You can also consider what kinds of articles will be relevant to your needs, then use search filters to narrow your results to fit those criteria. For example, if you are looking for recent articles, some databases give you the option to filter by publication date.

It's a good idea to keep a record of your searches: a list of what keywords or filters you've used, on what website, and what you were able to find with each search. This can help you locate sources again later, and have a record of what has worked well so you don't repeat work.

Resource links: The collapsed "Where to search section" below describes some options of where you may be able to find information and documents, as well as support services that could help you in your research. "Research strategies" contains more information on research strategies and approaches.

Open web (search engines like Google, Bing, DuckDuckGo ):

• Tools for searching for Open Access articles ( CORE plug-in , OA button )
• Advanced Google search tips
• Grey literature search tips  - grey literature is information produced outside of traditional publishing and distribution channels - things like newsletters, working papers, speeches, reports, and policy literature. It often comes from NGOs , government, industry, and other organizations.

Potentially useful collections:

• SFU list of Open Access databases
• Directory of Open Access Journals
• Academic library databases -- use Open Access filters in search ( SFU guide , UBC guide )
• Open content on JSTOR  -- a digital library of academic journals, books, and primary sources in the humanities and social sciences
• Downtown Eastside Research Access Portal  -- contains research and related materials relevant to Vancouver's Downtown Eastside
• Cochrane  Library  -- a collection of databases with evidence to inform healthcare decision-making, including systematic reviews, controlled trials, etc. (not all Open Access content, but many articles are)
• Candid. Issue Lab  -- an online collection of free research, evaluations, case studies, toolkits , etc.
• Frontier Life  -- a digital collection of primary source documents relating to colonialism in North America, Australia, Asia, and Africa

Paid databases:

• How to effectively search databases for journal articles

There are a few other resources that may assist you in your search or provide you access to additional materials. For example, public libraries may subscribe to databases that would then be free to patrons to access. Academic libraries also sometimes allow guests to visit in person and use university computers to access their electronic resources like databases. Other options include:

• Paid searching services ( InfoAction  at the Vancouver Public Library, for example)
• Professional organizations you are a member of may also have their own independent library collections
• JSTOR free account  - a digital library of academic journals, books, and primary sources in the humanities and social sciences
• You may qualify for the Community Scholars Program
• Start your research here -- an overview of the research process
• Library Research Skills -- interactive Canvas tutorial from the SFU Library that covers understanding assignments (or in your case, your research needs), narrowing your topic, and finding background sources, scholarly books, and articles. Geared towards students but may still be useful
• Finding articles: Advanced search techniques -- overview video of advanced search techniques that are especially useful when searching databases
• Search tips for Google, Google Scholar, DuckDuckGo , and other search engines  -- advanced search techniques for web search engines
• The Beginner’s Guide to Business Research -- from the UBC Small Business Accelerator 
• How to Conduct Market Research for Nonprofits Like a Pro - Pollfish Resources -- includes suggestions for sources for nonprofit secondary market research

Screen the results you're getting: are they relevant to the topic you've chosen? Do they fit the criteria you've selected for retrieval? You don't need to read the full article at this stage -- you can read the abstract or skim headings. If the article looks relevant, save the full text to read once you reach the synthesis stage.

Evaluating sources:

• Evaluating Sources - from the University of the Fraser Valley on scholarly vs. popular sources, news sources, images, and the "filter bubble"
• Evaluating Information Sources - from the University of British Columbia on evaluation frameworks and checklists
• CASP Checklists - checklists for evaluating methodology and study design

Choosing relevant sources for your topic:

• Choosing Sources - Sheridan College resource with questions to reflect about the type of information you're seeking
• Choosing the Best Sources and Evidence - University of Arizona Global Campus resource on selecting strong and relevant evidence
• How do I choose which sources to use? - Tips from Imperial College London to quickly identify whether information is relevant to your research

You’ll be doing a lot of reading, so keep notes on each source you find. This can be done in the notes section of your citation manager, or your own document.

The other articles your sources are citing can clue you into other important research in the field -- especially if they appear in multiple of your sources.

Recognizing patterns or themes (i.e. in findings, specific aspects of your topic studied, methods of research, conclusions) will be useful when you begin your write-up to help you link articles together or contrast them.

• Spying on a conversation [video] - tips and tricks on identifying relevant information in a literature review search, 4:43 - 8:54 is particularly relevant for the synthesis step
• Read & Take Notes - Researching the Literature Review - guide from Oregon State University on strategies for note-taking during a literature review

The form of your finished product may differ based on your audience, needs, and purpose. Should the write-up be thorough or brief? Casual or formal tone? Purely text, or with visuals?

Generally, a literature review should contain:

• An introduction -- where you explain why you've conducted this research, your context, and give readers a preview what you'll discuss and how that will be structured
• You don't need to fully summarize each article, and you also don't need to include every article on a topic -- just what's relevant to you!
• Element of analysis/critique  -- consider which sources you find particularly useful, and the positives or flaws they may have
• Conclusion -- how does it all add together? Does anything seem to be missing from the scholarship as a whole? Did you learn anything that's useful to your organization and its practices?

There are many possibilities to shape the format to your needs. Your literature review could contain an executive summary to explain your project and call out key findings. It could end with recommendations for action in your organization and beyond. It could take the form of an interactive web page. It could have bulleted summaries, photographs, and graphs.

See below in the "Examples" section to see some possible structures that incorporate some of these elements.

• Academic writing: What is a literature review? - guide from the SFU Student Learning Commons on what should be included in a literature review and how to organize it
• Literature Reviews - guide from the University of North Carolina at Chapel Hill on writing a literature review. "Strategies for writing the literature review" and "Begin composing" sections may be most helpful in how to create your write-up

Revisit: who was your original target or imagined audience?

Now that you've conducted your research, are there any other groups (whether internal or external to your organization) who would be interested in what you've created? These could be community members, local leaders, professional organizations, or partner organizations you work closely with.

What methods are available to reach your target audience and other potential groups you've identified?   Trade publications, blogs, email lists, or conferences might be good places to share your work. Internally, newsletters, meetings, and emails could be effective.

 Planning for your project's future

Keeping notes on your process (searches, sources, etc.) throughout your research allows you or others in your organization to pick your work back up later, or to replicate your process on a different topic.

Ensure your notes are kept somewhere secure and reliable, where others in your organization can also access it as needed.

Review discipline styles

Each discipline has its own style for writing a literature review; lit reviews in the sciences will look different from those in the social sciences and humanities. The best way to become familiar with lit reviews in your field of study is to look at published examples and note how they present the information. Literature reviews may appear as the introduction to a journal article, as an in-depth "review article," or as part of a dissertation or thesis. Below are a few examples.

Literature Review Examples

• Racism’s effect on depressive symptoms: Examining perseverative cognition and Black Lives Matter activism as moderators The literature review is the first part of this article from Journal of Counseling Psychology .
• Racial and ethnic disparities in severe maternal morbidity prevalence and trends The introduction to this article from Annals of Epidemiology reviews the literature.
• Social media effects on young women’s body image concerns: Theoretical perspectives and an agenda for research This entire article from Sex Roles is a literature review.
• La Douleur Exquise : Neoliberalism, race and the un/making of blackness in the 21st century Chapter one of this sociology dissertation is the literature review.
• A protracted war for order: Police violence in the twentieth century United States This article from History Compass is a historiography, which is similar to a literature review. Learn about the differences through this video .
• Black queer womanhood matters: searching for the queer herstory of Black Lives Matter in television dramas This article from Critical Studies in Media Communication shows how scholars in literary and film studies establish a theoretical lens using the literature.
