The Lens uses the OpenURL standard in combination with OCLC’s WorldCat repository of Library resolvers to implement OpenURL. This implementation of OpenURL passes the metadata for a scholarly work along to the WorldCat registry, which uses the IP address of the user to redirect the request to the user’s institution OpenURL resolver. Depending on the institution’s subscriptions and access to services, the resolver will provide the user access to the available version(s) of the scholarly work to which the institution has access.
