In December 2023, OCLC announced the addition of WorldCat Entities URIs (Uniform Resource Identifiers) for Persons, Places, and Events to WorldCat records as $1 links in 100, 600, 647, 651, and 700 MARC fields. As a next phase, OCLC will begin adding WorldCat Entities URIs for Works to 758 fields in WorldCat bibliographic records. These 758 fields (Resource Identifier fields) will have this structure:

758__ $i [relationship_in_languageof_040$b]: $a [placeholder_for_label_+material_type] $1 [placeholder_for_WorldCat_entityID] $4 https://id.oclc.org/worldcat/ontology/hasWork

Example for English language of cataloging:

758__$i has work: $a HBR's 10 must reads on managing people Vol. 2 (Sound) $1 https://id.oclc.org/worldcat/entity/E39PCGDbpB6QKpK4gc9MwdDFVd $4 https://id.oclc.org/worldcat/ontology/hasWork

Example for French language of cataloging:

758__ $i a pour œuvre: $a Le mouvement chrétien-social dans le canton de Genève (Text) $1 https://id.oclc.org/worldcat/entity/E39PCYvWdGxTkMYkvJgfF78Phw $4 https://id.oclc.org/worldcat/ontology/hasWork

For other languages of cataloging, the $i will be omitted as we work to collect translations that accurately convey the relationship.

Adding WorldCat Entities URIs for Works will happen in stages over the next several weeks, beginning on Saturday, January 27.

Enriching WorldCat MARC bibliographic records with WorldCat Entities URIs establishes a bridge between MARC data and linked data, providing a starting point for connecting data across local systems and workflows and for using linked data functionality in local discovery systems.

Note for WMS Institutions: The nightly refresh of your institution's data into the WorldShare Reports and Report Designer environment may be delayed by up to 8 hours. If your institution has scheduled reports set to run during the data refresh window, these may be impacted. To view when your library’s data was last refreshed, please consult the Data Last Refreshed reports for the respective data domains (e.g., Cataloging).
