 What is a digital object identifier, or DOI?

A digital object identifier (DOI) is a unique international identifier assigned to electronically available academic content, which provides a persistent link to the content location on the Internet. Providing a DOI prevents dead links and makes academic papers more easily accessible and citable.

 How a DOI is indicated on the OUKA website

When a DOI is assigned to OUKA content, following information is displayed on relevant pages on the OUKA website.


With a DOI string indicated in the citation information or a similar section, a permanent link to the intended content can be provided.
