Q. I have the same Author and Date for 2 different sources, how do I cite them in-text?


In APA, if you have the same author and the same date for two different sources:

  • Add a letter to the year.
  • The letter corresponds to the order they are on the Reference page.
  • They will go in alphabetical order on the Reference page by the title of the source


Mastin, L. (2018a). Ancient Greece Homer. Classical Literature. Retrieved from website address.

Mastin, L. (2018b). Timeline. Classical Literature. Retrieved from website address.

In-text citation:

Ancient Greece information will be (Mastin, 2018a)

Timeline information will be (Mastin, 2018b).

  2. Yes, if you use two articles by the same author and both articles do not have a date, then the example you provided is correct.
