4.5 How to Cite with APA


This guide is based on the 7th edition (2020) of the Publication Manual of the American Psychological Association.

In-text citations

In text citations include the surname(s) of the author(s) and the year of publication. Follow these guidelines to format your in text citations correctly.

1. How names are displayed depends on the number of authors:

One author: (Hanlon, 2007)
Two authors: (Rosa & Seibel, 2010)
Three or more authors: (IJsseldijk et al., 2015)

2. To cite multiple works at once, list the works in alphabetical order, by author last name.

(Arnaud, 2015; Hanlon, 2007; Torras, 2016)

3. If you are quoting a paper, include the page number of the quotation as follows:

(Mathevon et al., 2017, p. 2353)

Reference list citations

Reference list citations change depending on the type of item you are citing. Examples are below.

Notes for all citations:

  • Citations have a hanging indent, that means every line after the first line is indented to the right.
  • For all references, include the DOI (a unique identifier for each article) if available, or a URL if there is no DOI.
    • It should be formatted https://doi.org/[doi number]
  • All titles should be in sentence case.
    • Capitalize the first word of title, first word of subtitle and proper nouns.
