Ask Us! National University Library

A persistent URL (PURL), or permalink, is a durable link that connects you directly to an article, eBook, or other item in the Library. Persistent URLs can be helpful if you wish to share a library resource with a classmate or an instructor, or if you wish to quickly link back to a resource. PURLs also help us remain in compliance with copyright rules when sharing and linking to Library resources.

For Navigator Search and the EBSCO platform, the permalink is the URL in the address bar. There is no longer a separate link. 

See our Persistent URLs Guide for detailed information, including the Persistent URL Student Guide (located on the bottom left). This guide provides instructions for how to locate PURLs in the various Library databases.
