MicroCheck: for catalog conversion and updating

MicroCheck is provided by the vendor, a company that sells books, library supplies and automated services to libraries, as part of a catalog conversion service that company offers. That is, converting catalog records to machine‐readable form. The vendor maintains computer‐stored cataloging records. During the conversion process these are matched against the customer library's own cataloging records. The price of the conversion process is based on the number of matches anticipated between these two sets of records.
