An APA reference list comprises the publication details of the studies that specifically quote or support the ideas and concepts presented in a paper. Cite sources in the text, with a narrative or parenthetical citation, and include corresponding reference entries in the reference list.
An APA bibliography is similar to a reference list because it also includes full reference entries for sources cited in the text. However, they also include other sources that support or give background for further research related to the listed source.
An APA annotated bibliography includes short annotations below the reference entry in a separate paragraph(s). Annotations summarize and/or describe a source in detail.
