Finding a DOI

A DOI (digital object identifier) is a string of numbers and letters assigned to an electronic publication. It serves as a permanent link to the source.

Find it

It is found near the publication information at the top of an article or on the full item record in a database. On OneSearch, it is found in the “Preview” drop-down.

Search it

With just the DOI number, you can search for an article on OneSearch or another search engine. This is especially helpful if you find a source in another publication’s reference list and want to access it.

If the article does not come up in OneSearch, try searching the number on doi.org.

Cite it

When citing an electronic article, use the DOI (when available) in place of the URL to document the location of the source.
