A DOI or Digital Object Identifier is an alpha numeric name that identifies digital content such as a journal article or an e-book. The DOI can appear in any of the following formats:
1.  doi:10.1111/j.0013-2004.2005.00001.x


It is unique to each piece of digital content and provides a persistent link to that content no matter where it is located on the internet.

DOIs are increasingly being used in article and e-book databases, and are usually included as part of the citation details for a particular piece of work. The APA (American Psychological Association), Chicago Manual of Style and similar organisations now recommend that DOIs be used in referencing.

Using APA 7 DOIs are always formatted as a URL (https)

Using APA 6 any of the above three formats can be used, but the format you choose must be used consistently throughout the reference list.

If you have the DOI of a resource, you can:

  • Check if the University Library provides access to the full text content
  • Verify a reference
  • Search Summon or the internet with the doi alone and locate the article or any item that has cited it.
