A literature review summarizes and synthesizes the existing scholarly research on a particular topic. It identifies key contributions and gaps in the literature to provide context and focus for further inquiry. The document outlines a four-step process for conducting an effective literature review: 1) selecting a topic, 2) performing a comprehensive literature search, 3) reading sources strategically to evaluate findings and relationships, and 4) writing an organized synthesis that constructs an argument with evidence while maintaining an objective voice.
