On April 25, 2024, OCLC expects to install changes to WorldCat Validation, including the following new features and enhancements:

• OCLC-MARC Validations of New MARC Codes Announced January 23-March 26, 2024
• Decommission of encoding level (ELvl) values I and J
• WorldCat Entity duplicate check

The following bug fixes will also be included:

• Correction to validation for Data Provenance Subfields 

Correction to validation for 6xx fields when replacing a record

These features and enhancements 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, April 2024 at oc.lc/validation-release-notes for more details of the changes that we hope to install on April 25, 2024.
