Persistent Uniform Resource Locator (PURL)

I'm not sure why these never have taken off like wildfire. There is a need for a system to redirect users to the proper item on the Web. The co-operative upkeep of links saves time and ensures that the links are checked and corrected more often. The server software is free. In addition, OCLC provides a site for those who do not wish or need to install the resolver.

Beside OCLC, the GPO is using them. When I found a bad link I e-mailed them and it was fixed, not only for me but also for all who had that MARC record. CONSER is conducting a study of using them. Why are not these being used by Web rings, surely each site would share many of the same links. Municipalities and states could set one up covering sites in their geographic area.
