The American Psychological Association updated their citation style, known as APA Style, in October 2019. These are a few changes:
- References are streamlined. Publisher location - city and state - is no longer required in citations for books.
- More fonts are allowed. Recommended fonts are 11-point Calibri, 11-point Arial, 10-point Lucida Sans Unicode, 12-point Times New Roman, 11-point Georgia, or 10-point Computer Modern.
- Use DOIs and URLs as hyperlinks beginning with “http:” or “https:”. Do not use the label "DOI:". For example, use https://doi.org/xxxxx
- Do not add a period after the DOI or URL because this may interfere with link functionality.
- Student papers no longer need a running head across pages.
- Use one space after a period at the end of a sentence unless your instructor asks otherwise.
- In-text citations are simplified: Citations with three or more authors include only the name of the first author followed by "et al."
