The APA Style Blog (http://blog.apastyle.org/), managed by the American Psychological Association, is an official resource for updates and clarifications regarding APA style.
Here's some updates that you should see:
- How to cite a journal article, whole book, edited book chapter, or website in your table and figure (http://blog.apastyle.org/apastyle/2016/01/navigating-copyright-part-4.html). While the APA manual shows how to cite a journal article in tables and figures in Chapter 5 and gives a formula for wording copyright permission footnotes in section 2.12, this blog post is a welcome addition.
- The new DOI format APA is more flexible (http://blog.apastyle.org/apastyle/digital-object-identifier-doi/). The current APA manual (6th edition), is fairly strict with how an author should cite DOIs, i.e. "doi:" as a string - rather than the DOI in a URL. However, the APA style blog indicates that authors may now use either the "doi:" string, e.g. doi:10.1037/rmh0000008, or the DOI in a URL, e.g. http://dx.doi.org/10.1037/rmh0000008 . Please note: APA does not permit the use of "Retrieved from" with the URL version of the DOI.
- How to cite some newer or less common resource types not listed in the APA manual, e.g. a TED Talk, YouTube video, news report. Of course, you may not need to cite any of the resource types listed. Just know that the APA style blog might have an answer if the APA manual doesn't.
Here's useful advice from the APA style blog:
