Literature Review & Synthesis

Turn a collection of articles into a scholarly argument that establishes what is known, debated, and still unresolved.

A literature review is not an annotated bibliography

The goal is synthesis. Instead of reporting one article at a time, organize scholarship around concepts, themes, patterns, disagreements, methods, and gaps that matter to the study.

Use a literature matrix

A matrix can track citation, purpose, theory or framework, method, sample, findings, limitations, and relevance to your study. The value is not the spreadsheet itself; it is the ability to compare studies across common dimensions.

Move from summary to synthesis

  • Group studies by idea rather than by author.
  • Compare where findings converge and diverge.
  • Notice differences in populations, settings, and methods.
  • Identify what the literature can and cannot yet support.
  • Use transitions that show relationships among sources.

Establishing a gap

A research gap should be supported by evidence, not simply asserted. A gap may involve an underexamined population, context, relationship, process, methodological limitation, or unresolved scholarly disagreement. Avoid claiming that “no research exists” unless that statement can truly be supported.

Clarity check: By the end of the review, a reader should understand why your research problem remains important and how your proposed study fits the scholarly conversation.
Use the literature to strengthen your framework and proposal rationale.
