An annotated bibliography is a list of sources, such as books, articles, and websites, that includes a brief summary and evaluation of each source. Each entry typically consists of a citation in a specific format, like APA or MLA, followed by a short paragraph that explains the source's relevance, credibility, and usefulness for a particular research topic. Creating an annotated bibliography helps researchers organize their sources and understand the context of their research. It also aids in identifying gaps in the literature and can serve as a valuable reference tool for future projects or assignments.
