APA Citation Style

The Four Citation Elements

APA utilizes the author-date citation system. Within the text, articles are cited with the author's last name followed by the date. These citations can also be found in a table, figure, footnotes, or an appendix. For every citation that is within the text, there must be a corresponding full citation in the reference list. There are four main components to a citation in the reference list for every type of information resource:

In-Text Citation Formats

Parenthetical citations

Both the author and the data, separated by a comma, appear in parentheses for a parenthetical citation (American Psychological Association, 2020, p. 263).1  

1. This quote was used from page 263 from the Publication manual of the American Psychological Association seventh edition. For statements that are not direct quotes, omit the page number. 

Narrative citations 

The American Psychological Association (2020) states that the author element appears in running text and the date follows in parentheses immediately after the author name (p.263).2

2. In the example above the page number had to be included because the quote was closely paraphrased. 

Reference Page

The Reference list starts on a new page. The word "References" should be centered, bolded, and placed before the reference list entries

  • Create a reference list entry for every in-text citation
  • Order reference list entries alphabetically by author 
  • Double space 
  • Use a hanging indent for each reference

In-Text References - Quoting

Direct Quotes

  • Always include quotation marks around the copied words.
  • Use parenthetical or narrative citation style for in-text
    • Parenthetical citations either follow immediately after the quotation or at the end of the sentence.
  • Always include author, date, and page number
    • If a source has no date, use n.d. 
    • To signify a quote comes from a singular page, use p. (e.g. p. 231). If a quote spans multiple pages, use pp. (e.g. pp. 345-346). If quoting from discontinuous pages, separate page numbers with commas (e.g. pp. 126, 148).
    • If a source does not have page numbers, signify the quote by listing either the paragraph number (e.g. para. 4) or heading/section name (e.g. Center for Disease Control and Prevention, 2020, "Watch for symptoms" section). 
  • For quotes 40+ words use a blockquote 

 

Examples

Narrative: 

Klein (2000) wrote that some management theorists suggest, “Successful corporations must primarily produce brands, as opposed to products” (p. 3).

Parenthetical: 

Some management theorists suggest that successful corporations must primarily produce brands, as opposed to products (Klein, 2000, p. 3).

Quotes with 40+ words

Examples:

For pediatric liver transplants researchers found: 

These findings might have implications for further development of allocations rules for pediatric liver transplant recipients in a sense that small children and infants are well served with left lateral graft even in large-for-size situations, whereas small-for-size situations that especially occur in larger children weighing 25–50 kg should be avoided (i.e., by allocation of whole organs from pediatric donors instead of smaller left lateral grafts from adults) (Herden et al., 2013, p. 1223).

In-Text References - Paraphrasing

Paraphrasing is expressing an idea from another’s work into your own words or by rephrasing the information.

  • Include the author’s surname and copyright year.
  • It is recommended but not required to include page or paragraph numbers when paraphrasing.
  • It is recommended to paraphrase rather than quote repeatedly.

Examples:

Klein (2000) suggested that management theories, developed in the mid-1980s, put forth the idea that branding is as important to corporate success as the actual product that is produced.

OR

It has been suggested that management theories, developed in the mid-1980s, put forth the idea that branding is as important to corporate success as the actual product that is produced(Klein, 2000).
