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


In APA, when you have the same author and the same date for two different sources, you add a letter to the year.

The letter corresponds to the order they are on your Reference page. They will go in alphabetical order on your Reference page by the Title of the source. 


Mastin, L. (2009a). Ancient Greece Homer. Classical Literature. Retrieved from http://www.ancient-literature.com/greece_homer.html#Biography

Mastin, L. (2009b). Timeline. Classical Literature. Retrieved from http://www.ancient-literature.com/timeline.html

So your in-text for Ancient Greece information will be (Mastin, 2009a) and your in-text for Timeline information will be (Mastin, 2009b).

You can read this article at the official APA Style blog for more information: How to Cite Multiple Works by the Same Author(The example they use is for two book entries, but the principle and the answer is the same as for two websites.)

You can find out more information about APA Reference pages at the APA Help guide.

  2. Hello,

    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.
