Library Location and Library Look up results are zero for merged OCLC numbers when the frbrGrouping parameter is off
When an OCLC number has been merged under another record, the merged OCLC number is in the 019 field of that bibliographic record. Using the merged OCLC number in a query correctly pulls the record which includes the 019 field for all SRU queries and Single Bibliographic record queries. However, for Library Location requests, the merged OCLC number only works correctly if frbrGrouping is set to “on” or on by default. When the frbrGrouping parameter is set to “off” the merged OCLC number request for Library Locations incorrectly results in indicating there are no holdings.
