WorldCat Metadata API 2.0 release notes, April 2025

Records containing errors that have no significant impact on effective use of the record can now be added and replaced

You can now add or replace bibliographic records containing errors that have no significant impact on the effective use of the record. Correcting them is optional. Previously, some minor validation errors prevented users from adding or replacing a bibliographic record. For example, leaving the fixed field element Festschrift (008/30) blank is a minor level validation error that required correction, but now it is acceptable to add or replace a bibliographic record. 

All validation errors can still be viewed using the validateFull parameter with the "/manage/bibs/validate/{validationLevel}" endpoint. 

This enhancement applies to Record Manager as well. See release notes.
