Literature reviews are crucial in Communication Research Methods, providing a comprehensive overview of existing research and establishing the foundation for new studies. They help contextualize research questions, identify gaps, and establish theoretical frameworks, guiding researchers towards novel and valuable directions.

There are various types of literature reviews, including narrative reviews, systematic reviews, and meta-analyses. Each serves different purposes and requires varying levels of analytical rigor. The process involves defining research scope, searching for sources, evaluating quality, organizing literature, and synthesizing information to create a coherent understanding of the topic.
