Each citation style handles this situation a little bit differently! Here are specific examples of how it works in the three major citation styles:
In-Text Citations
When an author or author(s) published multiple sources in the same year, include a lowercase letter immediately following the date. Begin this lettering with "a" and continue in alphabetical order.
| General Format | For Example | |
|---|---|---|
| Parenthetical |
(Author, Publication Datea) (Author, Publication Dateb) (Author & Author, Publication Datea) (Author & Author, Publication Dateb) |
(Winston, 2017a) (Winston, 2017b) (Kelly & West, 2018a) (Kelly & West, 2018b) |
| Narrative |
Author (Publication Datea) Author (Publication Dateb) Author and Author (Publication Datea) Author and Author (Publication Dateb) |
Winston (2017a) Winston (2017b) Kelly and West (2018a) Kelly and West (2018b) |
