A digital object identifier (DOI) is a unique alphanumeric string assigned to identify articles and provides a persistent link to its location. A DOI starts with the number 10.

• Not all articles will have a DOI.

The DOI can be found:

• At the top or bottom of the first page of the article near the copyright information:
• In the database search results or article record:

If you already have the DOI, you can use it to locate your article:

1.  From the Library's home page, directly under the main OneSearch box, select CitationLinker. 

2. OR, add the DOI to the end of the following web address: http://dx.doi.org/.

For example: http://dx.doi.org/10.1111/j.1541-0072.2009.00314.x

If you have the citation, use CrossRef to locate the DOI. 

1. Check your article and its journal site for the DOI.

2. If not found in the article or at the journal site, use CrossRef to search for your article with its citation information.

Note: If you do not find a DOI at the publisher site, in the journal article, or in CrossRef you can assume that your article does NOT have a DOI.
