APA General Rules

  • Titles of works are in sentence case: Capitalize the first word, the first word after a colon, and any proper nouns. Otherwise, lowercase.
    • Example: Modern library services: An overview of Leslie J. Savage Library
  • If available, APA 7 requires a DOI for all works that have one — whether print or digital. If a print work does not have a DOI do not include it in the reference citation.
    • A DOI, or Digital Object Identifier, is a string of numbers, letters and symbols used to permanently identify an article or document and link to it on the web. A DOI will help your reader easily locate a document from your citation. Think of it like a Social Security number for the article you’re citing — it will always refer to that article, and only that one. While a web address (URL) might change, the DOI will never change.
  • URLs are optional. If you want to include the URL, place it at the end of the citation.

Basic Format for In-Text Citations:

Parenthetical citation: (Gleick, 1987)

Narrative citation: This is a fact, according to Gleick (1987).

If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference and may omit the page numbers.
