Overview

The LibraryCloud Item API OAI-PMH (https://www.openarchives.org/OAI/openarchivesprotocol.html) provides an application-independent interoperability framework based on metadata harvesting.

The LibraryCloud OAI-PMH Data Provider provides access to metadata about pre-defined sets of items in the Harvard Library collections. For the purposes of this API, an “item” is the metadata describing a catalog record within the Harvard Library. LibraryCloud Item API searches over 20,000,000 aggregated metadata records. Records are sourced from ALEPH for over 13,500,000 open access bibliographic records, VIA for over 4,500,000 visual information components, and OASIS for almost 2,000,000 archival finding aid componentsOAI "sets" are pre-defined and named as "collections" in the LibraryCloud collection database.
