The PURLZ Persistent URL Server version 1.4 is now available. See the PURLZ Downloads area to get your copy now. This release improves handling of URLs with query strings and special characters. It is recommended for immediate use by all PURL server operators.
PURLs are Web addresses or Uniform Resource Locators (URLs) that act as permanent identifiers in the face of a dynamic and changing Web infrastructure. This capability provides continuity of references to network resources that may migrate from machine to machine for business, social or technical reasons. Details are available on the PURLZ community site.
