On February 8, 2024, OCLC installed changes to WorldCat Validation. See the WorldCat Validation Release Notes, February 2024 for full details.

 This validation installation includes the following new features and enhancements:

• OCLC-MARC Validations of New MARC Codes Announced September 12-December 05, 2023
• MARC 21 Bibliographic Update No. 37 (Announced December 2023)
• MARC 21 Authority Update No. 37 (Announced December 2023) to the Validation Rule Set that Includes All Valid Elements of MARC 21 Authority Format. These changes apply only to the OCLC-MARC Authority validation rule set that includes all valid elements of MARC 21 Authority Format. Name Authority Cooperative (NACO) participants cannot use these authority format changes in the LC/NACO Authority File at this time. The Library of Congress and OCLC will announce the implementation of these elements for use in name and subject authority records in the LC/NACO Authority File at a future date.
• MARC 21 Holdings Update No. 37 (Announced December 2023)
• Edit Change to Encoding Level (Elvl) 8 Bibliographic Records

The following bug fixes have also been included:

• Correction to drop-down for Subfield $2 in Holdings Field 506
• Correction of MARC relator code dcg to dgc

These enhancements and fixes are the result of announcements of new MARC elements and codes by the Library of Congress as well as feedback and requests from members of the OCLC cooperative.

See the WorldCat Validation Release Notes, February 2024 at oc.lc/validation-release-notes for more details of the changes installed on February 8, 2024.
