Instructions and guidelines for ensuring persistent access from links to database content.

About Persistent URLs

Persistent URLs (also called PURLs, stable URLs, persistent links, or durable links) are internet addresses that remain constant. They are provided by many library online databases for consistent access to individual full-text articles when links are needed, e.g., in course management systems such as Brightspace.

Because most of these are paid-for subscription databases with licensing agreements, and are not freely available on the web, proper linking using these persistent URLs is required.

Using links to library resources

The best way to reference individual articles is through Primo, the libraries discovery tool.

Here is an example:

  • Use the COPY THE PERMALINK TO CLIPBOARD tool

  • This link will always come back to the Full Text links in Primo shown in the red box.



Most individual databases have tools for creating Permalinks. They vary from provider to provider. 

  • Here is the linking screen for Ebsco databases:

  • Here is ProQuest:

Important Tips

  • Always test the persistent URL you create from both on campus and off campus.
  • While persistent URLs are consistent, they may not be "permanent," as databases and vendors occasionally revamp their procedures. Although this does not happen often, please check your links from time to time.
  • Do not add spaces to URLs.
  • It is a good idea to include the full citation (author/ article title/ journal/ volume/ issue/ page/ date) with your link.
