What purl.org said about itself, 2006
Quoted from the site's AboutUs wiki page in each year it changed (1 version). These are the page's own words at the time, not AboutUs's assessment. New words · dropped words
2006
A PURL is a Persistent Uniform Resource Locator. Functionally, a PURL is a URL. However, instead of pointing directly to the location of an Internet resource, a PURL points to an intermediate resolution service. The PURL resolution service associates the PURL with the actual URL and returns that URL to the client. The client can then complete the URL transaction in the normal fashion.
