Cite a source within a source (secondary sources)

For sources that you have not actually seen (the primary source) but that are referred to in another work (the secondary source):

• In the reference list, provide an entry for the secondary source that you have read
• In the text, identify the original work and write “as cited in” the secondary source that you have read.

For example, if Bennett’s work is cited in a book by Stone (2013) and you didn’t read Bennett’s original work, list the source you did read (in this case Stone) in the reference list.

Cite secondary sources sparingly – for instance, when the original work is out of print, unavailable or only available in a language you don’t understand.

• See Secondary Sources in the APA style website for more information.
• In a long or complex work (a book for example), you may help a reader locate the section you used by citing the part of the work in the in-text citation (e.g., “p. 176” in the examples above).
