An annotated bibliography is a list of sources, such as books, articles, and websites, that includes a summary and evaluation of each source. Each entry typically contains the citation in a specific format, followed by a brief description of the content and its relevance to a particular research topic. This helps researchers understand the value of each source. Creating an annotated bibliography is useful for organizing research and demonstrating the depth of investigation into a subject. It can also assist in identifying gaps in the research and guiding future studies. Overall, it serves as a helpful tool for academic writing and research projects.
