APA citation style - 7th edition

Introduction

This guide provides a basic introduction to the APA citation style. It is based on the 7th edition of the Publication Manual of the American Psychological Association published in 2020 (2019). Copies of the manual are available at the Vanier Library's Reference desk and Webster Library's Ask Us! desk, in both Libraries' reference collections and on 3-hour reserve. The call number for the manual is BF 76.7 P83 2020.

The Publication Manual is generally used for academic writing in the social sciences. The manual itself covers many aspects of research writing including selecting a topic, evaluating sources, taking notes, plagiarism, the mechanics of writing, the format of the research paper as well as the way to cite sources.

This guide provides basic explanations and examples for the most common types of citations used by students. For additional information and examples, refer to the Publication Manual.

In-text citations - overview

When using your own words to refer indirectly to another author's work, you must identify the original source. A complete reference must appear in the Reference List at the end of your paper.

Chapter 8 of the Publication Manual provides further explanations and examples of in-text citations.

Authors

One author
  • In most cases, providing the author's last name and the publication year are sufficient:
    Smith (1997) compared reaction times...

    Within a paragraph, you need not include the year in subsequent references.

    Smith (1997) compared reaction times. Smith also found that...
Two authors
  • If there are two authors, include the last name of each and the publication year:
    ... as James and Ryerson (1999) demonstrated...
    ... as has been shown (James & Ryerson, 1999)...
3 or more authors
  • If there are three or more authors, include the last name of only the first author followed by "et al.":
    Wottom et al. (2017) found that...
    ... was also noted (Wotton et al., 2017)...
Corporate authors
  • The names of groups that serve as authors (e.g., corporations, associations, government agencies, and study groups) are usually spelled out each time they appear in a text citation. If it will not cause confusion for the reader, names may be abbreviated thereafter:
    First citation: (National Institute of Mental Health [NIMH], 1999)
    Subsequent citations: (NIMH, 1999)

Citing specific parts (pages, sections, & paragraphs)

  • To cite a specific part of a source, indicate the page, chapter, figure, table or equation at the appropriate point in the text:
    (Czapiewski & Ruby, 1995, p. 10)
    (Wilmarth, 1980, Chapter 3)
  • For electronic sources that do not provide page numbers, provide a heading or section name, abbreviated heading or section name, paragraph number, or a combination of heading name and paragraph number.
    (Myers, 2000, para. 5)
    (Bruce, 2020, “Why Individual Research Consultations” section)
    (Beutler, 2000, Conclusion section, para. 1)
  • For audiovisual works, such as TEDTalks, provide the time stamp of where the quote begins.
    "... we first of all need to consider emotional intelligence as a crucial skill in our society..." (Hacker, 2018, 6:10)

Citing traditional knowledge or oral traditions of Indigenous peoples

  • If the information is recorded and recoverable by readers, cite the source in your text and include it as an entry in the reference list. Be sure to examine published work to ensure that information it is providing is both accurate and appropriate before citing it.
  • Oral Traditions or Traditional Knowledge that is not recorded should have as much detail as possible in the parenthetical citations. In this circumstance, there would be no reference list entry. For more information, refer to section 8.9 of the Publication Manual

Secondary sources (indirect citation)

  • When citing a work which is discussed in another work, include the original author's name in an explanatory sentence, and then include the source you actually consulted in your parenthetical reference and in your reference list.
    Smith argued that... (as cited in Andrews, 2007)

Quotations

Direct quotations of sources

Direct quotations allow you to acknowledge a source within your text by providing a reference to exactly where in that source you found the information. The reader can then follow up on the complete reference in the Reference List page at the end of your paper.

Short direct quotations
  • Quotations of less than 40 words should be incorporated in the text and enclosed with double quotation marks. Provide the author, publication year and a page number.
    She stated, "The 'placebo effect,' ... disappeared when behaviors were studied in this manner" (Miele, 1993, p. 276), but he did not clarify which behaviors were studied.

    Miele (1993) found that "the 'placebo effect,' which had been verified in previous studies, disappeared when [only the first group's] behaviors were studied in this manner" (p. 276).
Long direct quotations
  • When including a quotation of more than 40 words, use a free-standing "block quotation" on a new line, indented 0.5 inches and omit quotation marks.
    Miele (1993) found the following:
    The "placebo effect," which had been verified in previous studies, disappeared when behaviors were studied in this manner. Furthermore, the behaviors were never exhibited, even when reel [sic] drugs were administered. Earlier studies were clearly premature in attributing the results to a placebo effect. (p. 276)

Further examples and explanations are available in Section 8.27 of the Publication Manual.

Reference list - overview

The alphabetical list of references that appears at the end of your paper contains more information about all of the sources you have used allowing readers to refer to them, as needed. The main characteristics are:

  • The list of references must be on a new page at the end of your text
  • The word References should be centered at the top of the page
  • Entries are arranged alphabetically by the author's last name or by the title if there is no author
  • Titles of larger works (i.e. books, journals, encyclopedias) are italicized
  • Entries are double-spaced (for the purposes of this handout, single-spacing is used)
  • For each entry, the first line is typed flush with the left margin. Additional lines are indented as a group, 0.5 inches to the right of the left margin (hanging indent)

Below are some examples of the most common types of sources including online sources (Web and databases). For more examples, refer to Chapter 10 of the Publication Manual.
