What is a persistent URL?

A persistent URL is one that never changes. Persistent URLs are designed so that your bookmarks and links don't break when a Web site gets updated.

On the ICPSR Web site, our study descriptions now have persistent URLs. If you want to bookmark a study page or link to it from your Web site, you should bookmark/link the persistent URL. In most browsers, you can do this by right-clicking on the link. In the menu that appears, there will be an option to add it to your bookmarks.
