APA 7th referencing style

This is a guide to using the APA 7th referencing style from the American Psychological Association. It is based on the Publication Manual of the American Psychological Association.

What is an indirect citation or secondary source?

An indirect citation or secondary source 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 reference.
  • Add "as cited in" before the author in the in-text reference. For 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.
