A literature review examines and evaluates previous research on a topic to establish what is known and unknown. It focuses on scholarly sources and analyzes them using the five C's: cite, compare, contrast, critique, and connect. The review has an introduction outlining the topic and context, a body section examining past research and identifying gaps, and a conclusion summarizing key findings and conclusions. Proper literature reviews are carefully organized, critically analyze sources, and clearly demonstrate how the current research builds upon past work.
