The document discusses the meaning and purpose of a literature review. A literature review systematically summarizes and synthesizes previous scholarly research on a particular topic. It identifies key writers and theories in an area of study. The literature review establishes the context and need for a research problem and shows what questions have been asked and what methodologies are appropriate. It prevents duplicating others' work and helps the researcher understand the topic better. A literature review should be objective, include relevant and recent sources, and not include too few or too many sources. It can enhance learning, analytical skills, and provide a framework for research projects.
