Citation styles change over time to adapt to a changing world and now APA 7th has been rolled out.
There are only a few major differences between APA 6th and 7th, some of which are the result of increasing digitization in academic publishing. A couple of examples:
You no longer have to try to figure out where the publisher is located geographically as this information no longer has to be included in the reference.
URLs no longer have to be preceded by “Retrieved from”, unless it is absolutely necessary to include a retrieval date.
One change that does not depend on the digital environment is the first time mentioning of a source. Regardless of the medium, all sources with three or more authors now require only the name of the first author followed by “et al.”
We have recently published a guide to APA 7th which is available to all students and members of faculty. You will find it on our website in the LibGuides section.
If you are a Mendeley user (or use another reference management software) we recommend that you change your settings to APA 7th. Instructions on how to do this are available on the front page of our APA 7th LibGuide..
