Local ILS: It is the responsibility of individual member libraries to have a process for recording retention commitments in their local catalogs. See the EAST 583 Working Group site for guidance on using the MARC 583 field in holdings records for this purpose. EAST does not need to be informed about retention commitments being transferred to different copies of the same title with the same OCLC number.
NOTE: If a library is moving a retention to a better OCLC record, move the Shared Print LHR to the new record. This will effectively register the retention commitment on the new record. Not that deleting and adding a new LHR does NOT register the commitment, nor set the Shared Print flag in OCLC.*
