APA7 Guide

• If you are citing two works by the same author in the same year, then the in text citations will look identical. To distinguish them you need to add a letter after the year – such as 2021a, 2021b. The alphabet order corresponds to their order in the reference list, so the source that comes first is ‘a’, second is ‘b’, and so on.
• DOIs can be identified using crossref.org. Not all books have a DOI.

For example:

Elkind (2007a) argues that children are often forced to grow up too quickly.

Children who are allowed to play spontaneously and without excessive structure have been shown to be happier (Elkind, 2007b).

For example:

“The average child today is forced through social pressure to grow up too fast” (Elkind, 2007a, p. 34).

“Spontaneous play is the cornerstone of developing a happy childhood” (Elkind, 2007b, p. 65).

• Reference each book separately as usual and make clear whether this is a second book by the same author or not by putting ‘a’ for the first book, ‘b’ for the second, ‘c’ for the third, and so on after the year.
