Definition of a PURL:A PURL (a persistent uniform resource locator) is an intermediate WWW address, which directs users automatically to a specific Web address for a given resource. Once set up, a PURL never needs to be updated, though the URL to which it points may change.
The following are general guidelines for determining if a PURL should be created for an electronic resource. If you are unsure about a particular resource, or have a suggestion, please contact Peter Martinez or Sally Lockwood.
Resources that already have persistent links. These include:
Previously assigned PURLS. Generally, these will be US government documents with GPO PURLS.
Links using the Handle System. These start with "hdl.handle.net".
DOI links. These start with "dx.doi.org".
Resources loaded from Serials Solutions and Ebsco. The Serial Solutions records have a 948 $hSerialSolutions in the Voyager record; the Ebsco records have a 948 $hEBSCO. All edits get overwritten in the subsequent record load.
Resources not directly or indirectly maintained by Cornell.
