The document discusses the importance of contextualizing research through a literature review. It helps researchers broaden their perspective on a topic, narrow down their research question, and locate relevant sources. The literature review is conducted in three stages - an initial review to select a topic, a thorough review to expand knowledge of theories, and a final focused review to refine the research question. Researchers must learn from past studies by understanding their methods, findings, and contributions to the field. Once sources are located through indices, databases, bibliographies and other means, the literature must be organized, summarized and synthesized to contextualize the research problem and inform the study.
