Why Literature Reviews Matter
A well-crafted literature review serves multiple purposes: it identifies gaps in existing research, establishes credibility, and provides the theoretical foundation for your study.
Step 1: Define Your Research Question
Before diving into databases, clearly articulate what you're investigating. A focused research question will guide your search strategy and help you stay on track.
Step 2: Develop a Search Strategy
Use a combination of databases like PubMed, Scopus, and Google Scholar. Employ Boolean operators (AND, OR, NOT) to refine your results. Keep track of your search terms and the databases you've used.
Step 3: Screen and Select Sources
Not every result will be relevant. Develop inclusion and exclusion criteria to systematically filter your findings. Read abstracts first to quickly assess relevance.
Step 4: Critically Analyze Each Source
For each source, consider:
- Methodology: Is the study design appropriate?
- Sample size: Are the findings generalizable?
- Bias: Are there potential conflicts of interest?
- Relevance: How does it connect to your question?
Step 5: Synthesize, Don't Summarize
The most common mistake is writing a series of summaries. Instead, organize your review thematically, identifying patterns, contradictions, and gaps across the literature.
Step 6: Write and Revise
Start with an outline organized by themes. Use clear topic sentences and transitions. Conclude by identifying the gap your research will address.
A great literature review takes time and iteration. Use tools like Researchly to organize your sources, annotate key findings, and track themes across papers.
