DOI stands for Digital Object Identifier.

Example DOIs are:

  • 10.1021/acs.orglett.6b03635
  • hdl.handle.net/1880/22716

A DOI is a permanent and unique code that assigned to an object, usually digital. Many journal articles and electronic books are assigned DOIs.

Why use a DOI?

Since a DOI is permanent and unique, the location of an object, e.g. its URL, may change, yet the object can still be identified by its DOI. This makes the object easy to find. 

DOIs are also used to gather altmetrics, an alternative to traditional publishing metrics that are calculated using social media activity.

We recommend you include a DOI, if supplied to you from a publisher, when depositing items into PRISM.

Libraries and Cultural Resources can mint DOIs on your behalf. Contact digitize@ucalgary.ca for more details.
