APA 7th Edition Citation Guide

In-Text: Secondary Sources

How to Use This Guide

Citations in APA style include two parts: (1) in-text citations, which are connected to (2) reference list citations.

This guide will help you create in-text citations that correlate with the corresponding reference list citations. Please see Reference Examples for more details on the reference list.

Note: All sources that are cited in the text must appear in the reference list at the end of the paper except for Personal Communications and similar unrecoverable sources.

Secondary Sources

A secondary source – which is also known as an indirect citation – occurs when your source cites or references another source, but you have not read or accessed the original author’s work. To handle this situation, you should:

  • Include (1) the original author and year and (2) the author and year of the work where quote/idea was found in the in-text reference.
  • Add "as cited in" before the author in the in-text reference.
Example

... (Harris, 2009, as cited in Lewis, 2019).

In the reference list, provide the details of the work in which you found the quotation or idea.
