ǂb Mode of issuance code

ǂ0 Authority record control number or standard number

Do not include subfield ǂ0 in WorldCat records. In the future, OCLC will provide the capability to output URIs in subfield ǂ0 based on the coding of subfields ǂa, ǂb, and ǂ2. For more information about subfield ǂ0, see Control Subfields.

ǂ1 Real World Object URI

Do not include subfield ǂ1 in WorldCat records. In the future, OCLC will provide the capability to output URIs in subfield ǂ1 based on the coding of subfields ǂa, ǂb, and ǂ2. For more information about subfield ǂ1, see Control Subfields.

ǂ2 Source of term

A MARC code that identifies the source list from which the mode of issuance is assigned. If the term appearing in the field is from a translated version of the original source document or list, the code must be followed by the appropriate 3-character MARC language code from the MARC Code List for Languages. The language code is separated from the subfield ǂ2 code by a slash. The term in subfield ǂa and the language code in subfield ǂ2 should be consistent with the language coded in field 040 subfield ǂb. For information about subfield ǂ2, see Control Subfields.

ǂ6 Linkage

Data that link fields when non-Latin script is entered. This subfield is system supplied and does not appear in OCLC online displays. Do not manually add subfield ǂ6. For more information about subfield ǂ6, see Control Subfields.

ǂ8 Field link and sequence number

For information about subfield ǂ8, see Control Subfields.

Punctuation

For records containing or omitting punctuation, follow these instructions:

  • Omit punctuation preceding each subfield
