This document defines the literature review and provides guidance on how to write one. It explains that a literature review reflects a summary of references and relates a researcher's work to others' work. The literature review should use reliable references from sources like academic journals and books. It should include the original authors' thesis statements, methods, findings, and conclusions to understand how the thesis was proven or not. The literature review paper usually has three sections: an introduction of the topic, summaries of referenced articles organized by purpose and findings, and a conclusion summarizing overall findings and questions still needing answers.
