Classification and Call number handling in Data Import
Statement of problem
In 2022, the Inventory and Data Import users discovered that MARC call number fields (such as 050, 060, etc.) with repeated fields or subfields are not handled properly when Instances, Holdings, and Items are created or updated.
The default MARC Bib-to-Inventory Instance mapping rules handle repeated classification fields fine, since classification is a repeatable field in the Inventory Instance. However, the current rules do not handle repeated subfields within a particular classification field properly. This is often the case with classification for bibliographies or juvenile materials.
The existing field mappings for call numbers in holdings and item records do not work properly if the mapped call number field is repeated in the MARC Bibliographic record. Since the call number field is not repeatable in the Inventory holdings or item record, the result is a call number that is a combination of the multiple MARC fields.
See below for tables of the affected classification fields and subfields and requirements.
Correcting the handling in Instances requires changes to the default MARC Bib-to-Inventory Instance map
Correcting the handling in Holdings and Items requires changes to the handling of mapped data in the call number fields of the Holdings and Item field mapping profiles
