Use the slides and examples included on the annotated bibliography page of the research guide:
https://libguides.usc.edu/DSW/annotatedbibliography to help you write an annotation for the source your chose.
Formatting guidelines (American Psychological Association. (2020). Publication manual of the American Psychological Association (7th ed).
https://doi.org/10.1037/0000165-000):
Refer to the APA writing and style guidelines, when writing the text of your annotations. Use 'in text' citations when you refer to multiple sources in an annotation.
If your instructor has not set any specific requirements, your annotated bibliography in APA 7th edition format (Section 9.51, p 307) should:
Be in alphabetical order, the same as you would any reference list
Have an annotation below the reference entry that is 0.5 inches from the margin, the same as you would format a block quote
