The ZMARCO Z39.50, MARC, OAI provider has been updated to use the latest version of the VB-ZOOM component. This should substantially improve ZMARCO's handling of different MARC records.
ZMARCO is an Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) 2.0 compliant data provider. The 'Z' in ZMARCO stands for Z39.50; 'MARC' stands for MAchine-Readable Cataloging; and the 'O' stands for OAI, as in the Open Archives Inititive. Essentially ZMARCO allows MARC records which are available through a Z39.50 server to relatively easily be made available via the OAI-PMH.
