A literature review surveys scholarly sources on a topic to provide an overview of current knowledge and identify relevant theories, methods, and gaps in existing research. It should analyze, synthesize, and critically evaluate sources, rather than just summarizing them. Conducting a literature review allows one to familiarize themselves with a topic, ensure they are not repeating past work, identify gaps their research could address, and develop a theoretical framework. The literature review typically comes early in a research paper, after the introduction, to ground the research in a scholarly field.
