Call numbers based on standard classification schemes not represented in the other call number fields. Field 098 is not part of the standard MARC 21 Bibliographic format. These schemes are usually available in printed or electronic form but are neither major schemes (e.g., Library of Congress or Dewey) nor local schemes.

Prefer other MARC 21 call number fields such as field 084 or field 086 with the scheme identified in subfield ǂ2.

Field 098 does not remain in the master record. It is retained in archive records, institution records, OCLC-MARC records, and exported records.
