In-Text Citation

Example of In-Text Citation for Multiple Resources by the Same Author, Published in the Same Year:

Several articles (Lenstra, 2017a, 2017b, 2017c; Lenstra & Baker, 2017) address public library trends.

Reference Citation

The three articles by Lenstra published in 2017 are arranged alphabetically by article title, and the letters a, b, and c are added to the date. For the other article by Lenstra and Baker published in 2017 is arranged alphabetically by the two authors' names so no letter is added after the year of publication. See also the APA Blog posting on this topic.
