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 Blackboard. 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 also important for copyright purposes.
For additional instructions on where/how to place URLs into Blackboard, see How do I add a persistent URL to a Blackboard course?
