How to Write an Annotated Bibliography with Multiple Authors
An annotated bibliography is an expanded form of a normal bibliography, which includes citations of references used in a research paper. In an annotated bibliography, a brief evaluative and descriptive paragraph that summarizes and reflects on the source's use in the research follows each citation. The annotation is typically no more than 150 words, and it backs up claims made in the research. When you use a source that includes multiple authors, you must include the names in a specific style in the citation and mention them in the narrative text.
Write the bibliographical citation in APA or MLA format based on the criteria for your research.
Cite multiple authors in the text of your annotated bibliography by writing both authors last names in parentheses. Join the author names together using an ampersand.
Add a comma after the second last name and close the parentheses. Add a period after the parenthesis.
Join the names of the multiple authors in the annotated bibliography with "and" when referring to more than one author in the narrative text. Follow the names with the year the work was published in parenthesis.
Write out all other authors for a reference if there are more than two authors for the first reference in the narrative text. All other references to the multiple authors should feature the last name of the first author, followed by "et al." and the year of the publication in parentheses.
