What is a DOI?

Answer

A Digital Object Identifier (DOI) is a persistent identifier (PID) or handle used to uniquely identify digital objects such as journal articles, book chapters, research reports, data sets, and official publications. A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. An example of a DOI is: https://doi.org/10.33178/alpha.26.01

You can search by DOI in OneSearch on the UCC Library website.
