Every WorldCat Entity has a unique identifier known as a Uniform Resource Identifier (URI). For bibliographic records without an identifier in a 100, 110, 600, 610, 647, 651, 700, or 710 field, you can search for a WorldCat entity of an applicable type and insert a $1 link with an appropriate identifier referencing that entity. Identifiers display in the $1 field as a clickable link, which will open in a new browser tab and take you directly to the reference in WorldCat Entities. Inserting an identifier in a 758 field will populate additional subfields.
MARC bibliographic field(s) | Entity types returned in search | Subfield(s) inserted |
---|---|---|
100, 600, 700 | Person, Agent, Family |
Note: For the 700 field, only insert an identifier for name headings (no titles). |
110, 610, 710 | Organization |
Note: For the 610 and 710 fields, only insert an identifier for name headings (no titles). |
647 | Event |

Note: For 610, 700, and 710 fields, identifiers should only be inserted for name headings, not titles.
Note: To use this functionality you must have an OCLC Meridian subscription and the appropriate role assigned to your WorldShare account.
The system will automatically attempt to add WorldCat Entities uniform resource identifiers (URIs) to WorldCat records when a candidate heading or headings are controlled. Candidate headings include those in the following fields: 100, 700 (name only), and FAST headings tagged 600, 647, and 651. If no $1 link is added for a candidate heading, please search for the entity and manually add the identifier if found. If a $1 link you believe to be incorrect has been automatically inserted into a candidate heading, please contact bibchange@oclc.org with details.
