- An article accepted for publication in a journal, described as "in press" or a "preprint", but not yet published is treated differently. Use the format for a printed journal article, but instead of the year include (in press) and omit volume, part and page details, as these cannot be confirmed until the article is actually published.
- Multiple author citations:
- 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.
- 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.
