Short version of the reference guide for APA 7th edition, a guide intended for students at the departments of Biology and Environmental Science at Lund University on how to format references according to the APA style.

Same author and date

Same author and date

If you are citing several works published by the same author in the same year, use lower case letter directly after the year to separate them. The same year-letter combination is used in both the in-text reference and the reference list.
