Annotated bibliographies consist of reference list entries followed by short descriptions of the work called annotations. Instructors generally set requirements, but APA Style guidelines still apply.
When writing the text of your annotations, consult the writing style and grammar guidelines in Chapter 4, the bias-free language guidelines in Chapter 5, and the mechanics of style guidelines in Chapter 6.
It is not necessary to cite the work being annotated in the annotation because the origin of the information is clear through context; however, do include in-text citations (see Chapter 8) if you refer to multiple works within an annotation to clarify the source.
Instructors generally set all other requirements (e.g., number of references, length and focus of each annotation). If there is something left out, format the annotated bibliography as follows:
Annotated bibliographies can also be created with APA’s cloud-based writing and research software called Academic Writer.
For an example of an annotated bibliography, refer to the Handouts and Guide tab on the APA Home page.
