Per EAST policy, EAST members are expected to record their commitments in their local ILS (guidance for adding commitments is available in EAST Member Resources). Consult with your local Technical Services staff on how to identify retained material in your ILS.
EAST commitments are also recorded in the Print Archives and Preservation Registry (PAPR), alongside commitments from the major shared print programs in North America. Note that CRL will do a free comparison of OCLC and/or ISSN numbers to the database in batch. Contact papr@crl.org for more information.
Retention commitments are also visible in OCLC’s Connexion, Record/Collection Manager, FirstSearch and various APIs. See the “Functionality across services” doc for descriptions of how to find Shared Print in each of these services.
