How do I do APA citations for multiple entries with the same author and date?
Yes, you would put the lower case "a", "b", "c" with the year in both the in-text citation and on your References page.
You would decide which entry gets the "a", "b", "c", and so on by alphabetizing the titles of the sources.
For example, your References page should look like this:
Whole Foods. (2013a). Careers. Retrieved from http://www.websites.com/this_page.html
Whole Foods. (2013b). Leadership team. Retrieved from http://www.website.com/a_different_page.html
Whole Foods. (2013c). Newsroom. Retrieved from http://www.website.com/yet_another_page.html
And your in-text citations would look like this:
Mr. Jones says his company "is really super great and people should work here" (Whole Foods, 2013a, para. 3).
