The document discusses the purpose and process of conducting a literature review. It defines a literature review as a critical evaluation and summary of published and unpublished works on a specific research topic. The literature review helps establish the theoretical background, clarify ideas, refine methodology, integrate new findings with prior knowledge, and identify gaps to form research questions. The process involves searching literature sources, reviewing and critiquing selected works, developing a theoretical framework to organize themes and issues, and constructing a conceptual framework to map the research problem.
