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.
We will create PURLs for:
- Local digital collections (such as DigitalCommons@ILR or MediaSpace) at the collection level & item level.
- Resources approved by the Database Review Committee (DRC) for listing in Databases.
- Other resources at the discretion of the E-Resources unit.
- Please contact e-resources@cornell.edu to request or update a PURL.
We will not create PURLs for:
- 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. These have a 948 $hSerialSolutions in the Voyager record. Any edits get overwritten in the subsequent record load.
- Resources not directly or indirectly maintained by Cornell.
