Book with multiple authors [from Print source using APA 5th ed.]


List up to six authors and abbreviate remaining authors as et al. (not italicised and with a full stop after "al". Always include a comma after the penultimate author's initials.

Don't panic if you see several dates inside the book. The date you need to use is the one which matches the edition of the book that you're using. Ignore any dates that are just listed as reprints or impressions. Look on the book cover and see if it says e.g. Fourth edition (it should also say this on the title page inside the book). In this case all that you need to show in your reference in the reference list is the date for the 4th edition of the book (and give the edition after the title of the book, immediately before the page numbers). Search for the book on the library catalogue to check the details needed for the reference if you are unsure.

  • With two authors both names should be listed in each citation e.g. (Duncan & Goddard, 2003, p. 99).
  • With three to five authors, name all authors the first time, then use et al. (and others). For example: the first time it would be (Moore, Estrich, McGillis, & Spelman, 1984, p. 33) and subsequent references to the same publication would use (Moore et al., 1984, p. 33).
  • For six or more authors, use et al. after the first author in all occurrences. (American Psychological Association, 2002, section 3.95; American Psychological Association, 2010, section 6.12).
  • Note that when the in-text reference occurs naturally within the sentence "and" should be used before the final author. But when the entire reference is enclosed in brackets the ampersand (&) should be used.
