How to cite multiple book chapters

So what is best practice when we needed to APA cite two or more chapters of a single edited book - or how many chapters can we/should we cite before we should cite the whole book and not individual chapters?

I decided the best strategy was to ask the APA gurus. I told them that I seemed to recall past supervisors requiring that - if I was drawing on more than one chapter, I needed to cite the whole book. But I also wondered if perhaps my impression was conflated with copyright law (that I needed to have a copy of the text and mayn't rely on a one chapter scan)? Plus I had a secondary question: what if we wanted to cite multiple chapters of an UNedited book - i.e. where the authors remain the same throughout? Was it different then? Did we need to cite the chapters or the book?

I had assumed that in both cases it would be the book. However, I was only half right!

The APA style gurus came back to me, which was BRILLIANT. They said that:

"In APA Style (7th ed.), there is no rule that says once [we] cite a certain number of chapters [we] must switch to citing the whole book". In fact, our "choice depends on what [we] actually used and what" gives our reader the most clarity (APA Style Blog, 3 April, 2026, personal communication). They noted that if we were "using specific chapters from an edited book written by different chapter authors, the best practice is to cite each chapter individually, no matter how many chapters from the same book" we decide to cite. They said this was "because each chapter is effectively its own source, with its own authorship and sometimes its own title and page range" we could "cite three, four, or more chapters from the same edited volume", then referencing "each chapter separately in the reference list".

But. If instead we were "referring to the book as a whole, for example, discussing the editor’s framing, the collection’s overall theme, or multiple ideas that are spread throughout without focusing on chapter authors, then" we should cite the "entire book" (APA Style Blog, 3 April, 2026, personal communication). As they point out, it is more about what we are "drawing on" rather than the number of chapters: substance over form.

And there is a second but. If we are citing an 'authored' book where all chapters are by the same authors, we "simply cite the whole book, because the entire work is by the same author(s)"(APA Style Blog, 3 April, 2026, personal communication). We could - if we needed to - direct our reader "to a specific chapter or section", directing our reader to a particular "chapter within the text, but the reference list entry remains the full book" (APA Style Blog, 3 April, 2026, personal communication).

APA style note that this was more "about scholarly practice" as opposed to "an APA formatting rule" (APA Style Blog, 3 April, 2026, personal communication). 

So that is: reference the entire authored book if using more than one chapter; reference the entire edited book if we are drawing on overall themes; reference individual edited chapter or chapters if drawing on chapter contents alone. 

And now we know.
