APA 7th Referencing

Sources referring to other sources (indirect citation)

A secondary source (indirect citation) is when the ideas of one author are published in another author’s text but you have not read or accessed the original author’s work.

  • Include both the original author and year and the author and year of the work where quote/idea was found in the in-text citation.
  • Add "as cited in" before the author in the in-text citation, e.g. (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.
