APA Style, 7th edition

APA style is maintained and updated by the American Psychological Association and has existed for nearly 100 years (since 1929). The most current APA guidelines come from the 7th edition of the APA Manual. This style is used in disciplines such as history, social sciences, and sciences.

APA style provides guidelines for references, in-text citations, paper formatting, and language use, which are explained in detail below.

References

Important Notes
  • The references page is the final section of your paper or project.
  • Reference pages are formatted with one-inch margins, a bolded header at the top, each line is double spaced with the second (and any following) trailing lines of a reference entry indented.
  • The page contains the citations for the sources of information you used in your paper. Every source in your paper should appear on the reference page and correspond to an in-text citation in the body of your paper.
  • Remember, your references page should follow APA Style guidelines so that a reader may locate your source.

Paper Format

In addition to reference and citation guidelines, APA Style requires specific paper formatting.

In-Text Citations

For both paraphrases and direct quotations, APA Style requires an author-date citation. From the sentence where your source and in-text citation appear, a reader could use the brief citation to refer to your larger, alphabetized references list to locate more information about the source. Every work in your reference list must be cited in the body of your paper.

Two options for in-text citations:

Parenthetical means the in-text citation is included at the end of a sentence (Author last name, date).

  • "Falsely balanced news coverage can distort the public’s perception of expert consensus on an issue (Koehler, 2016)."

Narrative means you are describing the author or their work in your written sentence.

  • "Koehler (2016) noted the dangers of falsely balanced news coverage."

Language Use

APA provides guidelines around inclusive language with the aim "to raise awareness, direct learning, and support the use of culturally sensitive terms and phrases that center the voices and perspectives of those who have been historically marginalized or stereotyped."
