A traditional bibliography is a list of sources consulted in your research. When you write a research paper, you include a bibliography, sometimes called a works cited list, so your readers and instructor can refer to the sources you used to support your ideas.
An annotated bibliography goes a step further and provides a summary of each source or an explanation of that source’s relevance to your research. Often, an annotated bibliography is a stepping stone in a larger research process like a capstone project, literature review, or scientific study.
