098  Other Classification Schemes (R)

Definition

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.

Field 098 does not remain in the WorldCat record. It is retained in exported records and records delivered via other services.

Prefer other MARC 21 call number fields such as field 080, or fields 084 and 086, in which the scheme is identified in subfield ǂ2 as appropriate based on Classification Scheme Source Codes.

If coding for a particular scheme is not found in Classification Scheme Source Codes, you may apply for a MARC code to officially identify the classification scheme. For details, see Source Codes for Vocabularies, Rules, and Schemes.

1st and 2nd indicators

00-99 The two indicators are assigned jointly to identify a two-digit code for Other Classification Schemes. In the list below, the first digit is the 1st indicator and the second digit is the 2nd indicator.
