What Is Literature Review?
A literature review dives into published information within a specific subject area or time frame. It usually combines summary and synthesis, where a summary recaps essential information from sources, and synthesis reorganizes or reshuffles this information. This reorganization might offer a new interpretation of old material or combine new with old interpretations. A literature review could also trace the intellectual progression of a field, including its significant debates. Depending on the situation, it may evaluate sources and advise readers on the most relevant.

2. Narrowing Your Topic and Selecting Papers for a Literature Review
When writing a literature review, narrowing down your topic and selecting papers judiciously is crucial. Start by considering your study area and engaging with your professor to gain insights. Brainstorm and peruse recent issues of periodicals related to your field to discern what topics interest you and other researchers. To focus your review effectively, limit the scope to a smaller topic area, for example, examining France's role in WWII instead of the broader WWII context.
3. Searching for Literature Sources
To commence the literature review process, define your source selection criteria. This could involve limiting articles to a specific date range, geographic region, or methodology relevant to your study. Utilize keywords to search library databases and explore the reference lists of recent articles to uncover additional valuable papers. It's essential to include studies that present perspectives contrary to your viewpoint to ensure a well-rounded and comprehensive review.
4. Reading and Evaluating Selected Articles
After gathering articles, it's crucial to read them thoroughly and evaluate their findings and conclusions. Pay attention to various aspects such as common assumptions among researchers, methodologies employed, experts frequently referenced in the field, conflicting theories or results, and the evolving popularity of different theories over time. This evaluation process helps you synthesize the information and draw meaningful insights for your literature review.
5. Organizing Selected Papers
Organizing selected papers is a crucial step in writing a literature review. Look for patterns in your findings and develop subtopics accordingly. Identify common or contested findings, significant research trends, and influential theories. Consider using a large table surface or digital tools to streamline this process and categorize your conclusions. You can structure your literature review effectively by creating headings and subheadings reflecting significant themes and patterns.
6. Developing a Thesis or Purpose Statement
Crafting a thesis or purpose statement is pivotal to writing a literature review. Summarize the conclusions you've drawn about the major trends and developments observed in the research conducted on your subject. This concise statement sets the tone for your literature review and guides your subsequent writing.
7. Writing the Literature Review
When composing your literature review, follow the organizational structure developed earlier. Ensure that each section flows logically, linking to the preceding and subsequent sections. Structuring your review by themes or subtopics rather than individual researchers or theorists enhances its coherence and readability.
8. Reviewing Your Work
The final step in writing a literature review involves reviewing your work for clarity and coherence. Examine the topic sentences of each paragraph to ensure they convey a clear position and logical progression. Make outlines for each section, modify content as needed, and read your work aloud to identify improvement areas. This meticulous review process enhances the overall quality of your literature review.
4 Ways To Structure Your Literature Review
1. Theoretical Literature Review
A theoretical review is a comprehensive survey of all the theories related to a specific research area. It can be divided into two main types: specific theory focus and general approach. The critical assessment of a chosen theory to evaluate its strengths and weaknesses is a fundamental part of the former, while the latter surveys all significant theories in a field to identify common themes and areas of disagreement. Theoretical literature reviews can be conducted at any research stage. Still, they are most beneficial when developing research questions and methodologies as they help to position research into the broader field and identify knowledge gaps to be filled.
2. Thematic Literature Review
A thematic review evaluates existing research on a particular topic and focuses on emerging themes or patterns. It helps identify gaps in current knowledge and areas that require future research. To write a successful thematic literature review, it is crucial to select a manageable topic, carefully analyze the existing work, and identify the central theme or pattern that emerges from the literature, which will be the review's focus.
3. Methodological Literature Review
A methodological review assesses all research methods used in a particular study area. It critically evaluates the strengths and weaknesses of different methods to determine the most appropriate one for answering a specific research question. This review helps researchers identify the best methods for their research inquiries.
Research methods are broadly divided into qualitative and quantitative approaches, with qualitative methods aiming to gather an in-depth understanding of a phenomenon and quantitative methods focusing on collecting and analyzing statistical data. A methodological literature review can compare and contrast the findings from both approaches.
4. Chronological Literature Review
A chronological review examines the development of a specific topic or idea over time to understand its evolution and the current debates around it. To write a chronological literature review, relevant sources must first be identified and analyzed to pinpoint critical trends and developments. The gathered information is synthesized to tell a coherent story about the topic's evolution.
