Uniform Resource Identifiers (URIs) in Bibliographic Records
Bibliographic records may contain URI links from external controlled vocabularies. For instance, name and subject headings may link among others to the Library of Congress (NAF and LCSH), the Virtual International Authority File (VIAF), the International Standard Name Identifier (ISNI) database, or the Open Researcher and Contributor ID database (ORCID). Genre and Form headings may link to LCGFT, AAT, etc., demographic terms may link to LCDGT, and fields 336, 337, 338, 340 may link to their corresponding RDA registries.
Individual catalogers at Yale do not devise and add URIs to bibliographic records. Most importantly, these external links should not be deleted when records are being imported from OCLC into the local system.
