case study vs literature review

How to Write a Case Study Analysis

Before writing a case study analysis, it is important to identify a relevant subject and research problem. While preparing to write, the author should critically assess the potential problem and the need for in-depth analysis. For example, hidden problems, outdated information, or a feasible recommendation are all indications that a problem lends itself to a case study. The introduction should not only include a problem statement but should also note its importance, provide background information, supply a rationale for applying a case study method, and suggest potential advancement of knowledge in the given field.

Literature Review

The key purpose of the literature review in a case study analysis is to present the historical context of a problem and its background based on academic evidence. Synthesis of existing studies contributes to the subsequent substantial aspects that should be taken into account:

• Identify the context of the problem under consideration and locate related studies, showing the link between them. Each of the academic pieces used to write a case study should make a particular contribution to understanding or resolving the target problem.
• Connect all the studies together and provide a critical appraisal. One of the most common mistakes is to merely present existing evidence without any analysis or clarification of how one or another research investigation relates to the problem.
• Discover and discuss any gaps in the literature, demonstrating how the case study adds more value and credibility to the available evidence. For example, if the case study focuses on strategies used to promote feminism, it is possible to explore the gap of how this movement is developing in the Middle East, where it is not as evident as in Western countries.
• Identify conflicts and contradictory issues that can be found in the literature. This helps in coming closer to the resolution of the problem. If, for example, two different approaches are regarded as mutually exclusive in one study, and the same approaches are considered compatible in another, it is an evident conflict. A discussion of such contradictory issues should be placed in the case study to suggest feasible solutions.
• Locate the case study in the context of the literature and within the larger scale. More to the point, by synthesizing the pertinent literature and indicating the role of the case study, the researcher shows that he or she has made essential efforts toward addressing the problem.

In this section, it is important to clarify why a specific subject and problem were chosen for study. A range of subjects is possible, and the type chosen will impact how the method will be described. The key types of subjects include phenomena, places, persons, and events.

• The investigation of a phenomenon as a target of a case study implies that certain facts or circumstances exist and require change and improvement. The behavioral and social sciences often require the study of challenging issues such as the causes of high employee turnover or a low level of motivation on the part of managers. In such a case, cause-and-effect relationships should be established to evaluate the environment.
• If an accident or event composes the basis of the case study, its time and place will set the specifics of the research. A rare or critical event as well as any one of a number of common situations may be selected; in any case, a rationale should be provided to support the choice. As a rule, rare events require forging a new way of thinking regarding the occurrence, while dealing with a commonly encountered situation is associated with challenging existing hypotheses. In both types of cases, the following elements should be included in the case analysis: timeframe, circumstances, and consequences.
• A focus on a person as the subject of a study refers to scrutinizing the individual’s experience, relationships, and behaviors. For example, a discussion of Mark Zuckerberg as the creator of Facebook requires identifying the background, conflicts, and positive and negative consequences of his contributions to society.
• A place as the subject of a case study should be special, and it should be clear to readers why a particular area or neighborhood was chosen. What is, for example, the aim of focusing on China and Japan instead of the United States when exploring homelessness issues?

An important part of case study research or development in the field of the social and behavioral sciences involves discussing and interpreting findings. Therefore, after a thorough literature review, it is necessary to compare, reiterate, and revise the findings based on the experiences reported in previous studies along with the writer’s personal understanding of the subject studied.

• The discussion section may start with a brief summary of the findings that are of the greatest importance and particularly thought-provoking.
• The results should be assessed in terms of the hypothesis and objectives of the research. Briefly reiterating these, indicate whether the data obtained have confirmed the hypothesis, the goal has been achieved, and the research tasks have been addressed.
• The researcher should indicate how the findings are consistent with the conclusions of other researchers and theories described in the literature review. Comparing and contrasting the findings with the articles mentioned in the literature review will be beneficial as this will support the importance of the new study.
• To identify the possibilities and ways of applying the results to solve practical problems, recommendations for practical implementation should be as specific as possible and describe actions that organizations or individuals can take to put the findings into practice.
• The advantages of the research methodology used and the limitations of the generalization of the results obtained should be clarified. Such a discussion is especially necessary in a case study since it demonstrates an understanding of methodological nuances.
• It is advantageous to outline the prospects and suggestions for further research on the given problem to expand the scope of application of the results. It is also crucial to point out possible ways to improve the methodology and organization of a case study analysis.

In the conclusion, restating the key findings and noting their importance is essential to allow readers to understand the key points of the case study report. The conclusion should be written concisely, including a description of the problem and elaborating on solutions while presenting the expected future effect of the actions proposed for practical implementation. While the body of the case study paper focuses on details, the conclusion contains a generalized scope of the research problem. However, overgeneralization as well as failure to specify limitations should be avoided. Only the documentary evidence serves as a basis for assumptions, and the statement of limitations will help preclude unjustified conclusions.

Many students struggle with how to do a case study analysis. Writing such an assignment is always daunting, as it requires you to analyze something and form conclusions based on your research.

It usually focuses on phenomena you can’t study in a typical way. Therefore, when writing such a text, you have to prepare thoughtfully. In the  PapersOwl article, you will find out what this academic writing is and how to write a case analysis.

What is a Case Study Analysis?

A case study analysis is a form of writing that analyzes a specific situation, event, object, person, or even place. The said analysis should be written and structured to lead to a conclusion. Typically, you cannot analyze the subject of this essay via quantitative methods.

Note that such studies can be used in various fields and require the use of many theories that can give you a unique approach to the matter. For example, you can write a paper like this about social sciences, business, medicine, and many other fields. Each of these will require a particular approach.

Difference Between Research Paper and Case Study

Both research papers and case studies share common features, yet they also differ in several key aspects. Hence, knowing these parallels and distinctions, you will be able to learn how to write a case study assignment correctly.

A case study introduction can present the topic but does not require a citation of other similar works or the writer’s opinion. In contrast, a research paper requires citations right from the introduction, as it builds on the research of others.

Furthermore, authors of case studies should share their insights and perspectives on the case they study. A major difference is that  research papers  concentrate on a specific issue and use solid evidence. In contrast, case studies examine a subject in depth, offer detailed information, and help develop critical thinking skills.

Types of Case Studies

When it comes to writing case study analysis, there are five types you must learn to differentiate. That is important because whether you get such an assignment, you will have to understand the task first and then start with the writing.

Here are the types of case studies which you will encounter most often:

• Problem-oriented – this type focuses on real-life situations or theoretical issues and aims to solve them. For example, “World Hunger.”
• The second type is critical , also known as innate . The goal is to investigate a specific case, particularly its effects and what causes them – “Why Toys Remain Gender Stereotyped.”

Historical case studies focus on events from our past. The text should contain information about a specific historical period of this type. Your goal will be to provide different perspectives of an event and parallel them to current-day issues. An example of such a topic is “Racism During Ancient Times – Roman Empire.”

• The illustrative or Instrumental type focuses on describing a particular event. Here you have to explain the event’s outcome and what you have learned from it. A sample of such a topic is “The Effects of Dance Therapy in Depressed Adolescents.”
• Collective case studies are the fifth type. They include a collection of data about a specific case you will use to compare. E.g., “The Management Leadership at Work.”
• Exploratory Case Studies . This type often applies in new fields of study or in cases where little data exists. An example of this type is “Initial Insights into Behavioral Trends in Cryptocurrency Trading.”

Writing a Case Study Draft

Creating a rough draft is the foremost step to take while writing such a paper. It is an essential step you must take, no matter how experienced you are. By doing it, you will be able to get more creative. In addition, you can explore options and decide on what to focus on more precisely, which will eventually result in a higher grade for your work.

So, sit down in a quiet place, bring an old-fashioned pen and paper, and start drafting ideas. Read them briefly while sipping on your tea and edit. After you have decided where your focus will lay, you have to develop these ideas and thoughts a bit more, then pick the best one.

How to Write a Case Study Outline

Creating a case study outline is an essential step in the writing process using the case study research method. Here’s how you can structure this preparation effectively:

• Conduct Research: Begin by using academic search engines like Google Scholar, or refer to books and published materials to gather relevant data. This research will help clarify the structure of your case study and determine the main points that need addressing.
• Formulate Your Thesis Statement: Develop a clear thesis statement that will guide the narrative of your case study. This statement should be based on the specific topic you have chosen.
• Outline Preparation
• Review Case Details: Thoroughly review the case you are analyzing to ensure a deep understanding of the subject.
• Note-taking and Question Formulation: Write down important notes and questions that arise during your review. Highlight relevant facts and critical data points that will support your analysis.
• Identify Problems and Causes: Identify the main problems and consider what their causes might be. This includes figuring out who is responsible and how these problems impact the company.
• Preliminary Research: Perform initial research to discover if similar problems have occurred previously and how they were resolved. This can offer insights into possible solutions and strategies for your case study.

The outline for your case study paper is essential to your writing process. It lets your professor assess your understanding of the topic, the correctness of your format, and the structure of your paper. They can spot any potential problems with your work. Having an outline serves as a guide for both you and your professor, making it easier to plan and write your paper . With the help of a well-crafted outline, your professor can navigate your paper more easily and spot any issues before they arise. Writing a case study can be challenging, but having a strong outline makes the process simpler.

A case study outline will most likely consist of the following sections and information:

• Case study title;
• Student’s name;
• Educational instructor’s name;
• Course name.

Introduction/Summary

• It briefly overviews your case study, thesis statement, and essential findings.

Main Body Paragraphs – usually three to five

• Literature Review/Background Information;
• Method/Findings;
• Discussion/Solutions/Recommendations.
• Repeat a paraphrased version of your thesis;
• Summarize your case study key points;
• Finish with a statement that can recommend the audience to read further by giving them thoughts to contemplate and develop new ideas.

Reference List or Bibliography

• List all the sources of evidence used to create your case study in your educational organization’s required citation style (APA, MLA, Chicago, Harvard, Turabian, etc.).

How to Write a Case Study

The way to write a case study is by strictly following the main idea of your thesis. You already know that a study’s main body consists of an introduction, literature review, method, discussion, and conclusion sections. Thus, all that is left is to focus on these parts and understand how to make them perfect.

• The Introduction/Summary: The introduction of a case study should start with a solid first sentence that will hook the reader. Afterward, you must explain the question you will be answering and why you are doing it. You should include some of the topic’s relevant history and details here. Also, you should explain how your case study will enrich the available information. Also, briefly summarize your literature review, which your findings will use as a base. Try to finish positively and make the reader see the benefits of reading your work.

• Background Information/Literature Review: ‍Structure and present the data from your academic sources . This section will show the reader how vital your work is and the basis for it.
• Method/Findings: This part aims to explain the case you selected, how it connects to the issue, and why you chose them. You can also add what methods you use. Here you must note that the data collection methods are qualitative, not quantitative, for case studies. That means the data is not random but well-structured and chronically taken from interviews, focus groups, and other sources.
• Discussion/Solutions: Restate your thesis but rephrase it, then draw your conclusions from what you have discovered via your research and link to your statement. Inform the audience of your main findings and define why the results are relevant to the field. Think about the following questions:

Were the results unexpected? Why/Why not?

How do your findings compare to previous similar case studies in your literature review?

Do your findings correlate to previous results, or do they contradict them?

Are your findings helpful in deepening the current understanding of the topic?

Next, explore possible alternative explanations or interpretations of your findings. Be subjective and explain your paper’s limitations. End with some suggestions for further exploration based on the limits of your work. ‍

• Conclusion: Inform the reader precisely why your case study and findings are relevant, and restate your thesis and main results. Give a summary of previous studies you reviewed and how you contributed to expanding current knowledge. The final should explain how your work can be helpful and implemented in future research.

Your instructor should have an excellent example they can show you, so feel free to ask. They will surely want to help you learn how to write a case study!

How to Analyze a Case Study

Analyzing a case study involves a structured approach that simulates real-life scenarios and is key to developing actionable insights. Here is a step-by-step guide adapted from Ellet, W. (2007) to help you effectively analyze a case study:

• Identify the Type of Case Study

Begin by determining the type of case study you are examining. This could be:

• Problems: Where something significant has occurred, and the cause is unknown.
• Decisions : Where a clear decision needs making, requiring options, criteria, and relevant evidence.
• Evaluations : Where you assess the effectiveness of a performance or outcome.
• Rules : These involve using quantitative methods to analyze a business area.
• Develop a Hypothesis

From the perspective of the protagonist, formulate a hypothesis to address the dilemma. Consider what you need to know about the situation:

• For problems: Understand the aspects, significance, and responsible parties.
• For decisions: Identify the options available, the stakes involved, and the decision-making criteria.
• For evaluations: Determine who or what is evaluated, the stakes, and the key evaluation criteria.
• Evidence and Alternatives

Evaluate your hypothesis by considering:

• The evidence supporting your hypothesis and any additional evidence needed.
• The weaknesses of your hypothesis and possible alternatives.

Writing a Case Analysis

Writing a case analysis involves a structured approach that enables you to communicate your understanding and analytical skills effectively. Here’s how you can craft your analysis to be insightful and comprehensive:

• Start with a Clear Definition or Position Statement

Begin your case analysis by stating your main conclusion, which serves as the answer to “What?” This initial statement should clearly outline what you have concluded from your analysis of the case.

• Build a Strong Argument with Evidence

Support your position statement with solid evidence, which answers “Why?” This evidence can be quantitative (numerical data) or qualitative (observations and interviews). The purpose here is to provide a foundation for your conclusions, showing how you arrived at them through logical reasoning.

• Outline a Chronological Action Plan

Detail the steps necessary to solve the problem, implement a decision, or enhance performance. This section answers “How?” and should include specific, realistic steps that address any major risks associated with your plan.

Tips for a Successful Case Analysis

• Aim to deliver concise and clear results of your analytical process rather than a simple summary or a complete transcript of your thoughts.
• Ensure your reader understands and is persuaded by your analysis by linking your conclusions directly to credible evidence.
• Discuss the advantages and also acknowledge any disadvantages of your conclusions to provide a balanced view.

How to Format a Case Study

Knowing how a case study analysis format should look is crucial. Therefore, you must know what the text structure should look like. The standard one contains about eight sections:

• Introduction/The Executive Summary: As the first part here, you have to hook the reader’s attention, so the introduction of the case study is the most important part of the writing.  Then present them with a brief overview of your case study analyses and their findings. Make sure to form a good thesis statement , as this is the pivotal point of your work.
• Literary Review/Background information: Similarly to other papers, in this part, you have to write your most important facts or findings while identifying the case issue.
• Method/Findings/Discussion: This section can be written separately based on how your text flows. Here you will have to explore more about the case and its findings. Allow yourself to go into more detail instead of just briefly covering them.
• Solutions/Recommendations/Implementation Part: You have to discuss the answers you came up with. Basically, you say why they are fit to solve the case and how you think they can be used in practice. Note that you must write only realistic and practical solutions for the problem. It’s possible to write testable evidence that can support your recommendations.
• Conclusion: Here, you are supposed to cover your whole paper briefly and even repeat the thesis (rephrased). Make sure to highlight the critical points of your case study.
• References or Bibliography: This section must include the sources from which you collected data or whom you consulted. Usually, this part is on a separate page, and the listing should be according to your academic institution’s requirements.
• Appendices (include only if applicable): It is usual for some parts of your materials to be too lengthy or unfit for the other sections of the case study. Therefore, you have to include them here. That can be pictures, raw data of statistics, graphs, notes, etc. The appendix section is strictly for subsidiary materials, do not put the most relevant ones here.
• Author Note: Remember that all educational institutions have their requirement for a case study format. The abovementioned is an example; thus, you may see a section or another is missing, or there are additional ones.

How to Create a Title Page and Cite a Case Study

A case study in APA format for students can differ from one institution to another. So, knowing your college or school requirements is crucial before you start writing. Nonetheless, the general one should look like this:

• Title – A header no longer than nine words has “Case Study” and reflects the content and the idea behind it yet is engaging to read;
• Write your full name;
• The name of your course/class;
• Next is your professor or instructor name;
• The university/school name;
• The date of submission.

When citing in your paper, you must ensure it is done accurately and in your academic style. If you are unsure how to do it, research the requirements and google “How to do a case study analysis in Harvard”, for example. Note that short citations can be in your text, but longer ones should be in the bibliography section.

Hruby, A. (2018). Hruby, A., & Hu, F. B. (2015). The epidemiology of obesity: a big picture. Pharmacoeconomics, 33(7), 673-689. www.sciepub.com. http://www.sciepub.com/reference/254744

Case studies strive to analyze an event, location, case, or person. They can be similar to research papers, so you must pay close attention to the structure and what your professor has requested from you.

Finally, the process of writing can be overwhelming due to the many sections. However, if you take the process step by step and do your preparations properly, you will have an easy time writing the paper. You can also look for assistance online – many services offer to order case study online help . With the right kind of assistance, you can be sure that your paper is of high quality and is due on time!

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.

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.

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.

Literature Review

• What is a Literature Review?
• What is NOT a Literature Review?
• Purposes of a Literature Review
• Types of Literature Reviews
• Literature Reviews vs. Systematic Reviews
• Systematic vs. Meta-Analysis

Literature Review  is a comprehensive survey of the works published in a particular field of study or line of research, usually over a specific period of time, in the form of an in-depth, critical bibliographic essay or annotated list in which attention is drawn to the most significant works.

Also, we can define a literature review as the collected body of scholarly works related to a topic:

• Summarizes and analyzes previous research relevant to a topic
• Includes scholarly books and articles published in academic journals
• Can be an specific scholarly paper or a section in a research paper

The objective of a Literature Review is to find previous published scholarly works relevant to an specific topic

• Help gather ideas or information
• Keep up to date in current trends and findings
• Help develop new questions

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.
• Helps focus your own research questions or problems
• Discovers relationships between research studies/ideas.
• Suggests unexplored ideas or populations
• Identifies major themes, concepts, and researchers on a topic.
• Tests assumptions; may help counter preconceived ideas and remove unconscious bias.
• Identifies critical gaps, points of disagreement, or potentially flawed methodology or theoretical approaches.
• Indicates potential directions for future research.

All content in this section is from Literature Review Research from Old Dominion University 

Keep in mind the following, a literature review is NOT:

Not an essay 

Not an annotated bibliography  in which you summarize each article that you have reviewed.  A literature review goes beyond basic summarizing to focus on the critical analysis of the reviewed works and their relationship to your research question.

Not a research paper   where you select resources to support one side of an issue versus another.  A lit review should explain and consider all sides of an argument in order to avoid bias, and areas of agreement and disagreement should be highlighted.

A literature review serves several purposes. For example, it

• provides thorough knowledge of previous studies; introduces seminal works.
• helps focus one’s own research topic.
• identifies a conceptual framework for one’s own research questions or problems; indicates potential directions for future research.
• suggests previously unused or underused methodologies, designs, quantitative and qualitative strategies.
• identifies gaps in previous studies; identifies flawed methodologies and/or theoretical approaches; avoids replication of mistakes.
• helps the researcher avoid repetition of earlier research.
• suggests unexplored populations.
• determines whether past studies agree or disagree; identifies controversy in the literature.
• tests assumptions; may help counter preconceived ideas and remove unconscious bias.

As Kennedy (2007) notes*, 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 original studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally that become part of the lore of 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 several approaches to how they can be done, depending upon the type of analysis underpinning your study. Listed below are definitions of types of literature reviews:

Argumentative Review      This form examines literature selectively in order to support or refute an argument, deeply imbedded 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 to make summary claims of the sort found in systematic reviews.

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. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication.

Historical Review      Few things rest in isolation from historical precedent. Historical reviews are focused 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 [content], but how they said it [method of analysis]. This approach provides a framework of understanding at different levels (i.e. those of theory, substantive fields, research approaches and data collection and analysis techniques), enables researchers to draw on 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, and helps highlight many ethical issues which we should be aware of and consider as we go through our 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 analyse data from the studies that are included in the review. 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?"

Theoretical Review      The purpose of this form is to concretely examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review help 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.

What's in the name? The difference between a Systematic Review and a Literature Review, and why it matters . By Lynn Kysh from University of Southern California

Systematic review or meta-analysis?

A  systematic review  answers a defined research question by collecting and summarizing all empirical evidence that fits pre-specified eligibility criteria.

A  meta-analysis  is the use of statistical methods to summarize the results of these studies.

Systematic reviews, just like other research articles, can be of varying quality. They are a significant piece of work (the Centre for Reviews and Dissemination at York estimates that a team will take 9-24 months), and to be useful to other researchers and practitioners they should have:

• clearly stated objectives with pre-defined eligibility criteria for studies
• explicit, reproducible methodology
• a systematic search that attempts to identify all studies
• assessment of the validity of the findings of the included studies (e.g. risk of bias)
• systematic presentation, and synthesis, of the characteristics and findings of the included studies

Not all systematic reviews contain meta-analysis. 

Meta-analysis is the use of statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects of health care than those derived from the individual studies included within a review.  More information on meta-analyses can be found in  Cochrane Handbook, Chapter 9 .

A meta-analysis goes beyond critique and integration and conducts secondary statistical analysis on the outcomes of similar studies.  It is a systematic review that uses quantitative methods to synthesize and summarize the results.

An advantage of a meta-analysis is the ability to be completely objective in evaluating research findings.  Not all topics, however, have sufficient research evidence to allow a meta-analysis to be conducted.  In that case, an integrative review is an appropriate strategy.

A literature review is a discussion of the literature (aka. the "research" or "scholarship") surrounding a certain topic. A good literature review doesn't simply summarize the existing material, but provides thoughtful synthesis and analysis. The purpose of a literature review is to orient your own work within an existing body of knowledge. A literature review may be written as a standalone piece or be included in a larger body of work.

You can read more about literature reviews, what they entail, and how to write one, using the resources below.

Organizational Tools for Literature Reviews

One of the most daunting aspects of writing a literature review is organizing your research. There are a variety of strategies that you can use to help you in this task. We've highlighted just a few ways writers keep track of all that information! You can use a combination of these tools or come up with your own organizational process. The key is choosing something that works with your own learning style.

Citation Managers

Citation managers are great tools, in general, for organizing research, but can be especially helpful when writing a literature review. You can keep all of your research in one place, take notes, and organize your materials into different folders or categories. Read more about citations managers here:

• Manage Citations & Sources

Concept Mapping

Some writers use concept mapping (sometimes called flow or bubble charts or "mind maps") to help them visualize the ways in which the research they found connects.

There is no right or wrong way to make a concept map. There are a variety of online tools that can help you create a concept map or you can simply put pen to paper. To read more about concept mapping, take a look at the following help guides:

• Using Concept Maps From Williams College's guide, Literature Review: A Self-guided Tutorial

Synthesis Matrix

A synthesis matrix is is a chart you can use to help you organize your research into thematic categories. By organizing your research into a matrix, like the examples below, can help you visualize the ways in which your sources connect.

Case Study | Definition, Examples & Methods

Published on 5 May 2022 by Shona McCombes . Revised on 30 January 2023.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organisation, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.

A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating, and understanding different aspects of a research problem .

Table of contents

When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyse the case.

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.

You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Prevent plagiarism, run a free check.

Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:

• Provide new or unexpected insights into the subject
• Challenge or complicate existing assumptions and theories
• Propose practical courses of action to resolve a problem
• Open up new directions for future research

Unlike quantitative or experimental research, a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.

If you find yourself aiming to simultaneously investigate and solve an issue, consider conducting action research . As its name suggests, action research conducts research and takes action at the same time, and is highly iterative and flexible. 

However, you can also choose a more common or representative case to exemplify a particular category, experience, or phenomenon.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:

• Exemplify a theory by showing how it explains the case under investigation
• Expand on a theory by uncovering new concepts and ideas that need to be incorporated
• Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions

To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.

There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews, observations, and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data .

The aim is to gain as thorough an understanding as possible of the case and its context.

In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis, with separate sections or chapters for the methods , results , and discussion .

Others are written in a more narrative style, aiming to explore the case from various angles and analyse its meanings and implications (for example, by using textual analysis or discourse analysis ).

In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.
