DOI Explained

You may have noticed a number at the end of journal articles or ebooks and wondered what it signified.

What is a DOI?

A DOI (digital object identifier) is a unique and permanent code assigned to many, but not all, electronically published sources. A DOI is a persistent link that will take you straight to a document no matter where it is located on the Internet. DOIs do not change.

When a DOI is used, no further retrieval information is needed to identify or locate the content. Include the DOI as the final component of your source citation.

Think of it as a "digital fingerprint" or an article's DNA!
