A persistent URL (PURL) is a durable link that connects you directly to an article, eBook, or other item in 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.

See our Locating Permanent Links or Persistent URLs (PURLs) Guide for detailed information. This guide provides instructions for how to locate PURLs in the various library databases.
