Understanding Literature Review

Purpose of Literature Review

The primary purpose of a literature review is to describe, summarize, evaluate, and clarify the prior research on your topic. It is a survey of information found in scholarly articles, books, and other literature related to your area of study. The literature review provides a critical analysis of the existing literature, highlighting the strengths and weaknesses of previous studies. It also identifies the gaps in the literature and suggests areas for future research.

The literature review serves several purposes, including:

Providing an overview of the existing knowledge on a topic
Identifying research questions and hypotheses
Identifying gaps in the literature
Providing context for your research
Identifying relevant theories and methods

Types of Literature Review

There are different types of literature reviews, each with its own purpose and focus. The two most common types of literature reviews are:

Narrative literature review: This type of literature review provides a summary of the existing literature on a topic. It does not follow a specific methodology but rather provides a broad overview of the literature.
Systematic literature review: This type of literature review follows a specific methodology to identify, evaluate, and synthesize the existing literature on a topic. It uses a predefined set of criteria to select the studies to be included and follows a rigorous process to ensure the quality of the review.

Planning the Review

Choosing a Topic

Choosing a topic is the first step in planning your literature review. Your topic should be specific, relevant, and interesting to you. To choose a topic, consider the following:

What is your research question or problem statement?
What are the key concepts or variables in your research?
What are the main themes or debates in your field of study?

Identifying Sources

Identifying sources is the second step in planning your literature review. You need to find and evaluate sources that are relevant to your research question or problem statement. Here are some tips for identifying sources:

Use relevant databases and search engines to find peer-reviewed articles, books, and other sources.
Use keywords and Boolean operators to refine your search and find relevant sources.
Evaluate the quality and relevance of sources by considering factors such as the author’s credentials, the publication date, and the methodology used.

Conducting the Review

Reading and Analyzing

The first step in conducting a literature review is to read and analyze the literature on your topic. This involves finding relevant sources, reading them carefully, and analyzing their content to identify key themes and arguments.

When searching for sources, it is important to use a variety of search strategies, including keyword searches, citation searches, and reference chaining. You should also be selective in the sources you choose to include in your review, focusing on those that are most relevant to your research question and that provide the most useful information.

Once you have identified relevant sources, you should read them carefully, taking notes on key ideas, arguments, and evidence. It can be helpful to use a note-taking system, such as a spreadsheet or a note-taking app, to organize your notes and keep track of important information.

After reading and taking notes on your sources, you should analyze their content to identify key themes and arguments. This involves looking for patterns and connections between sources, and synthesizing the information you have gathered into a coherent narrative.

Organizing Findings

The second task in conducting a literature review is to organize your findings into a coherent structure. This involves creating an outline or a conceptual map of your review, and organizing your sources and notes according to the main themes and arguments you have identified.

One effective way to organize your findings is to use a table or a matrix to summarize the key information from each source. This can help you to compare and contrast different sources, and to identify gaps and inconsistencies in the literature.

Another useful technique is to use headings and subheadings to structure your review. This can help you to organize your ideas and to guide your reader through the review.

Writing the Review

Creating a Thesis Statement

The first step in writing a literature review is to create a thesis statement. Your thesis statement should be a clear and concise statement that summarizes the main argument or point of your literature review. It should also provide a roadmap for the rest of your review, outlining the main themes and topics that you will be discussing.

To create a strong thesis statement, you should start by identifying the main research question or topic that your literature review will be addressing. Then, you should identify the key themes and ideas that emerge from the literature on that topic. Finally, you should distill these themes and ideas into a clear and concise statement that summarizes the main argument or point of your literature review.

Developing the Body

Once you have created your thesis statement, the next step is to develop the body of your literature review. The body of your review should be organized around the main themes and topics that you identified in your thesis statement.

To develop the body of your literature review, you should start by identifying the key sources that you will be discussing. Then, you should organize your sources into themes or topics, grouping together sources that address similar themes or ideas.

Once you have organized your sources, you should begin writing your review. In each section of your review, you should provide a summary of the main findings or arguments of the sources that you are discussing. You should also identify any gaps or limitations in the existing research and explain how your review addresses these gaps.

Integrating Sources

The final step in writing a literature review is to integrate your sources into your review. To do this, you should use a variety of techniques, such as summarizing, paraphrasing, and quoting, to incorporate the ideas and arguments of your sources into your review.

When integrating your sources, it is important to maintain a clear and coherent narrative throughout your review. You should also be careful to avoid plagiarism by properly citing your sources and using quotation marks when necessary.

Revising the Review

Editing for Clarity

Editing for clarity involves reviewing your literature review to ensure that it is easy to read and understand. Here are some tips for editing your literature review for clarity:

Use clear and concise language: Avoid using overly complicated language or jargon. Instead, use clear and concise language that is easy to understand.
Use headings and subheadings: Use headings and subheadings to organize your literature review and make it easier to navigate.
Use transitions: Use transitions to connect your ideas and make your literature review flow smoothly.
Check for coherence: Ensure that your literature review is coherent and that your ideas are presented in a logical order.

Proofreading

Proofreading involves reviewing your literature review for errors in spelling, grammar, and punctuation. Here are some tips for proofreading your literature review:

Take a break: Take a break from your literature review before proofreading it. This will help you approach it with fresh eyes.
Read it out loud: Read your literature review out loud to catch errors that you may have missed while reading silently.
Use spell check: Use spell check to catch spelling errors.
Use a grammar checker: Use a grammar checker to catch grammar errors.
Have someone else review it: Have someone else review your literature review to catch errors that you may have missed.

Citations and References

Citing Sources

Citing sources is an essential part of writing a literature review. It is important to give credit to the authors of the sources you use in your paper. This not only shows respect for their work but also helps to avoid plagiarism. There are different citation styles that you can use, such as APA, MLA, and Chicago. Your professor may specify which citation style you should use, so make sure to follow their instructions.

When citing a source, you need to provide the author’s name, the publication date, the title of the article or book, and the name of the publication. If you are citing a direct quote, you also need to include the page number. The citation should be placed in parentheses at the end of the sentence, before the period.

Here is an example of a citation in APA style:

According to Smith (2010), “Literature reviews are an essential part of research” (p. 15).

Creating a Bibliography

In addition to citing sources in your paper, you also need to create a bibliography or reference list. This is a list of all the sources you used in your paper, arranged in alphabetical order by the author’s last name. The bibliography should include the same information as the in-text citation, but in a different format.

The format of the bibliography depends on the citation style you are using. For example, in APA style, the bibliography should include the author’s name, publication date, title of the article or book, and name of the publication. It should also include the DOI or URL if available.

Here is an example of a bibliography entry in APA style:

Smith, J. (2010). The importance of literature reviews in research. Journal of Research Methods, 5(2), 10-20. doi:10.1007/s12345-010-0001-1

When creating a bibliography, make sure to double-check the formatting and accuracy of the information. A well-formatted bibliography shows attention to detail and enhances the credibility of your paper.

When writing a literature review, there are five rules to keep in mind. Firstly, you should define the scope of your review. Secondly, you should identify the key themes and concepts that you want to explore. Thirdly, you should critically evaluate the literature you have gathered. Fourthly, you should organize your literature review in a logical and coherent manner. Finally, you should be sure to cite your sources properly.
