How to Cite a Book With Three to Five Authors by using The American Psychological Association (APA) Referencing System. See Library APA referencing webpage for six or more authors.
The APA (American Psychological Association) style requires two elements: in-text citations throughout your assignment, and a reference list at the end.

Include information about a source within the text of your assignment:
  • the name of the author or authors
  • the year of publication
  • the page number (see below for further information)
Citations may be placed at the end of a sentence (before the concluding punctuation) in brackets
Quotation (exact words from the source)
Broudy (1998, p. 9) argues that “on the common criteria for schooling, our sample citizen has failed because he cannot replicate the necessary skill or apply the relevant principles”.

How to cite?

  • In a reference list
Krause, K.-L., Bochner, S., & Duchesne, S. (2006). Educational psychology for learning and teaching (2nd ed.). Melbourne, Australia: Thomson.
N.B. Use & between authors’ names, except when paraphrasing in text. When a work has three, four or five authors, cite all authors the first time, and in subsequent citations include only the first author followed by et al.
  • In-text citation
(Krause, Bochner, & Duchesne, 2006) then (Krause et al., 2006)
