APA 7th Style: Citing Secondary Sources - 'Cited in' Format

When citing someone else's citation in APA 7th style, you should follow these guidelines:

1. In-text citation: Use the phrase 'cited in' to indicate that you are citing a source that was cited by another author. For example, (Smith, 2000, as cited in Jones, 2010).

2. Reference list: Include the source that you actually consulted in your reference list. Do not include the source that was cited by another author unless you have also consulted it. For example, Jones, A. (2010). Title of article. Journal Name, volume(issue), page range.

3. Optional: If you have also consulted the source that was cited by another author, you can include it in your reference list as a secondary source. Use the phrase 'as cited in' to indicate that you are citing a source that was cited by another author. For example, Smith, J. (2000). Title of book. Publisher. (as cited in Jones, 2010).

Note: It is important to always try to consult the original source whenever possible in order to ensure accuracy and credibility of your work.
