There are many scenarios where a library may discover a metadata mismatch, including incorrectly cataloged reprints or incorrectly assigned OCLC numbers. Metadata errors should be reported using the EAST Reversal and Reallocation Requests form. If the mismatch is only the edition, and no other EAST libraries retain the edition you hold, please keep the retention, and register the retention on the correct OCLC number. See the OCLC Shared Print page for information on how to register, move or remove retention commitments.
