How to Write a Literature Review: 3 Minute Step-by-step ...
Step 1: Set Up Your Review Plan
A well-organized plan is the foundation of your literature review. Here's how to get started.
Focus Your Research Question
Begin with a clear, specific research question to guide your review. It should be narrow enough to stay focused but broad enough to uncover enough relevant sources.
To shape your research question:
-
Start Broad, Then Narrow
Begin with a general topic and refine it through reading and brainstorming. Concept mapping can help identify promising directions. -
Test Your Question
Ensure your question addresses a single issue, is feasible with available resources, offers depth for analysis, and aligns with your field of study. -
Get Early Feedback
Discuss your question with your advisor to refine it and identify potential challenges early on.
Create Your Search Plan
Use a structured approach to search for relevant sources. Here's a quick guide:
| Search Element | Example | Purpose |
|---|---|---|
| Keywords | "breast ADJ3 cancer" | Finds terms within three words of each other |
| Truncation | therap* | Captures variations like therapy or therapist |
| Wildcards | behavio?r | Accounts for different spellings |
| Boolean Operators | AND, OR, NOT | Combines or excludes terms |
- Use databases like JSTOR or PubMed for academic sources.
- Keep track of your search terms and results.
- Adjust your strategy for different databases.
- Include synonyms and alternative phrases to broaden your search.
- Refine your terms as needed to improve accuracy.
Set Your Schedule
Organize your work into phases with a clear timeline:
-
Initial Research (2–3 weeks)
Identify sources, read broadly, and fine-tune your search strategy. -
Detailed Review (4–6 weeks)
Dive deeper into reading, take detailed notes, and identify patterns or gaps in the literature. -
Analysis and Writing (3–4 weeks)
Synthesize your findings, write your draft, and revise thoroughly.
With a solid plan in place, you're ready to move forward and gather high-quality sources for your review.
Step 2: Find Quality Sources
To craft a strong literature review, you need to rely on trustworthy academic sources. Here’s how to locate and evaluate research materials effectively.
Choose Academic Databases
Start by using well-established academic databases that provide peer-reviewed content. For example:
| Database Type | Best For | Coverage |
|---|---|---|
| Scopus | Multidisciplinary research | 399,000+ books; extensive journal coverage |
| PubMed | Biomedical literature | 38+ million citations |
| Academic Search Complete | General academic research | 5,795 active full-text journals |
These databases offer access to high-quality research. Once you’ve chosen the right ones, use advanced search techniques to narrow down your results.
Master Search Methods
Finding the right sources requires a focused approach. Here are some tips to refine your searches:
- Start Broad, Then Narrow: Use general keywords initially, then refine with Boolean operators like AND, OR, and NOT.
- Leverage Advanced Search Features: Use tools like truncation (e.g., "educat*" for "education" or "educational"), phrase searching (e.g., "climate change"), and field-specific searches to pinpoint relevant results.
- Keep Track: Maintain a record of your keywords, databases, search results, and dates for easy reference.
Once you’ve gathered your search results, the next step is to evaluate the quality of each source.
Check Source Quality
Hector R. Perez-Gilbe, a Research Librarian at UC Irvine, highlights Scopus for its comprehensive output metrics. To evaluate sources, use the Big 5 criteria: Currency, Coverage, Authority, Accuracy, and Objectivity.
- Currency: Ensure the publication date is recent enough to be relevant.
- Coverage: Check if the material provides sufficient depth and aligns with your topic.
- Authority: Look into the author’s credentials and expertise.
- Accuracy: Cross-check information with other reliable sources.
- Objectivity: Be on the lookout for potential biases.
When prioritizing academic articles, focus on those that are:
- Peer-reviewed
- Cited by other scholars
- Transparent in their methodology
- Thorough in their literature reviews
- Authored by individuals with institutional affiliations
These steps will help you identify the most reliable and relevant materials for your literature review.

Step 3: Review and Connect Sources
Once you've gathered quality sources, it's time to dive deeper by analyzing and linking their insights.
Take Clear Research Notes
Use a synthesis matrix to keep your research organized. This tool helps you track essential details like citations, findings, methodologies, gaps, quotes, and page numbers.
| Source Citation | Key Findings | Methodology | Research Gaps | Relevant Quotes | Page Numbers |
|---|---|---|---|---|---|
| Author (Year) | Main conclusions | Study approach | Limitations noted | Direct quotes | Location |
| Smith (2024) | Increased engagement | Mixed methods | Small sample size | "Key finding..." | pp. 45–47 |
| Jones (2023) | Decreased retention | Quantitative | Limited scope | "Statistical..." | pp. 12–15 |
Tools like Sourcely can simplify this process by offering features to organize notes and generate citations automatically.
Find Patterns and Gaps
As you review your sources, focus on identifying:
- Common themes: Group findings or theories that align.
- Contradictions: Pinpoint conflicting results or perspectives.
- Research gaps: Highlight areas that haven't been fully explored.
- Methodological trends: Compare the approaches researchers have used.
For a structured analysis, try the Conceptual Synthesis Excel Dump (CSED) method, introduced by Raul Pacheco-Vega in June 2016. This technique helps you systematically organize and assess your data.
Map Your Findings
Visual tools can help you see how your sources connect. Consider these mapping strategies:
- Chronological Mapping: Show how research has evolved over time.
- Thematic Mapping: Group sources by shared themes or topics.
- Methodological Mapping: Compare different study designs.
You can also categorize studies based on whether they support, oppose, or offer alternative perspectives. This will help you build a stronger narrative and present a balanced view of the research.
Step 4: Write Your Review
Now that you've analyzed and organized your sources, it's time to turn your research into a clear and structured review.
Pick Your Format
Decide on the structure that best fits your research goals. Here are three common options:
| Format Type | Best Used When | Benefits |
|---|---|---|
| Chronological | Tracking the evolution of research | Shows how understanding has developed over time |
| Thematic | Addressing different viewpoints | Groups similar findings for easy comparison |
| Methodological | Examining various research methods | Highlights differences in approaches and their outcomes |
Choose the format that aligns with your research question. For example, use chronological to show progression, thematic to compare perspectives, or methodological to contrast approaches.
Write Strong Bookends
Your introduction should set the stage by defining the topic, providing context, explaining your organizational approach, and outlining the scope of your review. The conclusion, on the other hand, should tie your arguments together. Focus on connecting ideas rather than just summarizing.
"A good literature review is NOT simply a list describing or summarizing several articles; a literature review is discursive prose which proceeds to a conclusion by reason or argument."
Cite Sources Correctly
Select a citation style that fits your field, such as APA, MLA, or Chicago/Turabian, and integrate your sources smoothly into the text. Ensure accuracy and consistency by following these steps:
- Use quotation marks for direct quotes.
- Cite all paraphrased ideas.
- Stick to one citation format throughout.
- Double-check reference details for accuracy.
"Stigmatization of the mentally ill is caused by the public's belief in myths about the dangerousness of the mentally ill and exposing those myths can reduce stigmatization."
Using tools like Sourcely can make citation management easier. It helps you track your sources and ensures proper attribution, minimizing the chances of accidental plagiarism.
Once you've cited everything correctly, move on to tightening and refining your text during the final editing phase.
Step 5: Edit and Perfect
Check Your Flow
Go through your literature review to ensure everything connects smoothly. Pay close attention to how paragraphs and sections transition. Reading your work out loud can help you spot unclear parts and improve the overall clarity. Key areas to focus on include:
- Smooth transitions between paragraphs and sections
- Topic sentences that clearly guide the reader
- Logical development of arguments
- Maintaining a consistent and professional tone
Acknowledge Your Limits
Be upfront about the boundaries of your analysis. Identify the type of limitations - whether they're theoretical, methodological, empirical, analytical, or ethical - and explain their impact and any potential solutions. For example, if your review only includes English-language sources, note how this might exclude research from other regions.
Polish and Format
Make sure your review meets academic standards by taking care of the following:
- Citations: Ensure they are accurate and consistent.
- Formatting: Check headings, indentation, and pagination for uniformity.
- Grammar and Style: Fix any errors and refine your writing.
Place your limitations section in a clear and visible spot. This helps readers understand the context of your findings while showcasing your academic thoroughness.
For an extra layer of polish, tools like Sourcely can help ensure formatting consistency throughout your document.
