APA Style (7th Edition) Citation Guide: Secondary Sources

Formatting

Note: All citations should be double spaced and have a hanging indent in a Reference List.

A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.

Below is a link to an APA sample paper that contains instructions about how to format a hanging indent in a paper.

Secondary Sources

If you use a source that was cited in another source, name the original source in your signal phrase then write "as cited in" the secondary source in parentheses. List only the secondary source in your reference list.
