APA Style Guide - 7th edition

A guide to APA style

Notable Changes

Here are some notable changes between the Sixth and Seventh editions of the APA Manual:

  • Use one space after a period at the end of a sentence.
  • Student papers do not require running heads. 
  • Do not include city or state for publishers in the source element for a book. 
  • List up to and including 20 authors in a reference. 
  • All in-text citations for works with three or more authors use only the first author's name plus et al. 
  • All DOIs begin with; add the prefix to a DOI if it is not there.
  • If there is no DOI for a journal article, etc., from a database, DO NOT use a URL, permalink or database name.  Treat it as a print source.
  • What's new in the seventh edition Publication Manual from the APA Style Blog is a good source. 

For more details see pages xviii–xxii in the APA Manual.
