How to Write a Literature Review for a Dissertation or Thesis
Writing a literature review is a critical step in crafting any dissertation or thesis. It shows that you’ve read the existing research in your field and can analyze, summarize, and synthesize that knowledge effectively.
But students often get confused between summarizing articles and writing an actual review. This article will guide you step-by-step and help you avoid common mistakes, while also pointing you toward expert support if you need help.
📘 What Is a Literature Review?
A literature review is a structured analysis of scholarly sources (books, journal articles, etc.) relevant to your research topic. It serves to:
-
Show understanding of current knowledge
-
Identify gaps or controversies
-
Justify your research question
-
Provide a theoretical foundation
🧭 Structure of a Literature Review
Most reviews follow this format:
-
Introduction
-
Define the topic
-
Explain the scope of your review
-
State the purpose (e.g., identifying gaps, forming a theoretical base)
-
-
Thematic or Chronological Body
-
Group studies by theme, trend, or timeline
-
Summarize findings
-
Compare and contrast viewpoints
-
Evaluate the quality of each source
-
-
Conclusion
-
Summarize key insights
-
Highlight research gaps
-
Connect findings to your own project

🛠️ Step-by-Step Guide to Writing
1. Define Your Purpose
Ask: What does this literature review aim to prove? Is it background for your hypothesis? A critique of existing models?
2. Search Strategically
Use academic databases like JSTOR, Google Scholar, or your university’s library to find peer-reviewed sources.
3. Evaluate and Filter
Don’t just collect. Ask:
-
Is it relevant to your research question?
-
Is it recent and credible?
-
How has it been cited by others?
4. Organize Your Notes
Use a matrix to map authors, key points, findings, and relevance. This makes writing easier later.
5. Start Writing
Begin with your outline. Integrate sources smoothly. Avoid just summarizing—analyze and synthesize.
6. Edit and Refine
Focus on clarity, transitions, and correct referencing style (APA, MLA, Chicago, etc.).
🧩 Literature Review Example Snippet
While Smith (2019) argues that AI in healthcare improves patient outcomes, Johnson (2021) suggests these technologies create data privacy concerns. The contrast between these findings suggests a research gap in patient trust and data ethics in digital health.
This type of synthesis shows you’re not just listing ideas—you’re critically engaging with them.
❌ Common Mistakes to Avoid
-
Listing instead of analyzing
-
Using too many outdated sources
-
Not connecting studies to your research question
-
Failing to spot bias or methodological flaws in sources
-
Copying definitions or literature without proper paraphrasing
