Vendor-specific ordering data. OCLC batchloads the vendor records into WorldCat.
If a batchloaded vendor record matches an existing WorldCat record, OCLC adds the 938 field to the master record. If there is no match, OCLC adds a master record to WorldCat. In either case, OCLC sets the vendor's holdings and retains field 938 in the master record. You cannot add, change or delete a 938 field in a master record (you can add, change or delete a 938 field in your local copy of the record).
