Do you know Crossref? Crossref is an organization “working to make content easy to find, link, cite, and assess” (Crossref, 2016). One of their services is to register digital object identifiers (DOIs), and we follow their guidelines for display of DOIs.
Effective March 2017, Crossref has updated their DOI display guidelines, in part to ensure security (with https). For more details, seehttps://www.crossref.org/display-guidelines/ and https://www.crossref.org/blog/new-crossref-doi-display-guidelines-are-on-the-way/
Their new recommended format looks like this:
And here’s how that looks in an APA Style reference:
|Morey, C. C., Cong, Y., Zheng, Y., Price, M., & Morey, R. D. (2015). The color-sharing bonus: Roles of perceptual organization and attentive processes in visual working memory. Archives of Scientific Psychology, 3, 18–29. https://doi.org/10.1037/arc0000014|
Note the secure https and the simple URL prefix doi.org.
Although we recommend moving to the new format, in APA Style manuscripts, we will be accepting the older formats (doi:10.1037/arc0000014 or http://dx.doi.org/10.1037/arc0000014) or the new format (https://doi.org/10.1037/arc0000014).
We recommend that you pick one format to use consistently throughout a reference list.
We will begin using the new format in our examples on this blog from this point forward. But, to clarify, in your manuscripts or papers, all of the following are currently considered correct APA Style:
