The document discusses the purpose and process of conducting a literature review. It states that the literature review helps researchers understand the problem being investigated, determine what is already known about the key variables and concepts, identify gaps and inconsistencies, and decide on a research design. The literature review involves consulting primary sources like journal articles and theses to learn about existing theories and findings. Researchers must take notes to develop an agenda of topics and keywords to search relevant literature on. The literature is then analyzed, organized, and reported on to introduce and situate the present study within existing scholarship.
