Author, A. A. & Author B. B. (n.d.). Title of page [Format description when necessary]. Retrieved from

Referencing a Source Your Reader Can Access (Student Paper)
Arnett, P. (2020). Course outcomes [Lecture notes]. NMC Moodle.


  • Updated versus Reviewed Date for Online Works (9.15 in Manual)
    • If the page has a "last updated" date, and you're sure the material you're citing was updated, then use that date.
    • If the page has a "last reviewed" date, don't use it in your reference; the content probably wasn't updated. Use n.d.
  • "If you cite multiple webpages from a website, create a reference for each." (10.16 in manual)

In-Text Citations

In-text citations point the reader to more complete information in the reference list at the end of the paper.

Basic format: use the last name of the author followed by a comma and the publication year enclosed in parentheses: (Smith, 2007).

When doing a direct quote: include the page number should be included, or a pointer to the paragraph or section. If you are paraphrasing the page number is not required.

Signal Phrase: If you refer to the author's name in a sentence you do not have to include the name again as part of your in-text citation, instead include the date after the name and the page number (if there is one) at the end of the quotation or paraphrased section. For example:

Hunt (2011) explains that mother-infant attachment has been a leading topic of developmental research since John Bowlby found that "children raised in institutions were deficient in emotional and personality development" (p. 358).

A Work by Two Authors

Name both authors in the signal phrase or in parentheses each time you cite the work. Use the word "and" between the authors' names within the text and use the ampersand in parentheses. Examples:

In their research on therapy options, Key and Peel (2015) demonstrated...

(Key & Peele, 2015)

A Work by Three tor More Authors

(Pavia et al., 1993)

Unknown Author

If the work does not have an author, cite the source by its title in the signal phrase or use the first word or two in the parentheses. Titles of books and reports are italicized; titles of articles, chapters, and web pages are in quotation marks. APA style calls for capitalizing important words in titles when they are written in the text (but not when they are written in reference lists). Example:

A similar study was done of students learning to format research papers ("Using Citations," 2001).

Organization as an Author

If the author is an organization or a government agency, mention the organization in the signal phrase or in the parenthetical citation the first time you cite the source.

According to the American Psychological Association (2000),...

If the organization has a well-known abbreviation, include the abbreviation in brackets the first time the source is cited and then use only the abbreviation in later citations.

First citation: (Centers for Disease Control and Prevention [CDC], 2017)
Second citation: (CDC, 2017)
