Summary of notable changes (thanks to College of DuPage Library https://www.codlrc.org/APA_7)
· Website URLs no longer need to be preceded with “Retrieved from:”.
· Ebooks no longer require type of ebook to be listed (e.g. PDF, Kindle etc)
· Journal DOIs now displayed as a doi.org URL instead of “DOI:” prefix.
For example: “DOI: 10.1109/5.771073” becomes “https⁚//doi.org/10.1109/5.771073”
· The publisher location is no longer required.
For example: “New York: Macmillan” is now just “Macmillan”.
· The running head rules are “simplified,” and running heads are
not required for student papers
· The first in-text citation of a work by more than two authors may list
only the first author, followed by “et al.”
