Citing sources and avoiding plagiarism in your writing

Books & Ebooks

 In APA 7th edition, cite print books and electronic books in much the same way.  Place of publication is no longer included in print book references. For open-access eBooks, put the URL at the end if it directly takes you to the full text without logging in. If book has a DOI (especially ebook) you may include it at end of reference, in the form,


Author, A. A. (Year). Title of book. Publisher.



George, M. W. (2008). The elements of library research: What every student needs to know. Princeton University Press.

(George, 2008) (in-text citation)

Kleiser, G. (2008). Fifteen thousand useful phrases. Funk & Wagnalls; Project Gutenberg. (Original work published 1917)

(Kleiser, 1917/2008) (in-text citation)

Samanez-Larkin, G. R. (Ed.). (2019). The aging brain: Functional adaptation across adulthood. American Psychological Association.

Note: Your References list should list the entire work. In-text citations may (but don't always) cite specific pages. Source: Publication Manual 8.13, p. 264 (not included in APA Style website).

When citing in-text, it can be difficult if your eBook does not have a page number (most PDF books do). In this case, try to get as specific as possible by mentioning chapter, section, and paragraph numbers.

One of the author's main points is that "people don't rise from nothing" (Gladwell, 2008, Chapter 1, Section 2, para. 5).(example of in-text citation to a specific section of book).
