The elements of the annotated bibliography are a reliable sources related to your research topic, written in a citation format selected by your instructor or editor, and a summary of the article, webpage, etc. Do not copy the abstract of the article. The bibliography can also serve as a source for future research. Provide a thoughtful summary, with analysis or criticism, of why the resource can be used.
An option can be to write an introduction to discuss why the annotated bibliography is written.
Citation managers, such as EndNote and Zotero, can automatically create the citations. Perdue OWL shows examples of APA, MLA, Chicago, and AMA citation styles, especially if there is no example in the citation managers..
