Subfields

 
‡a Taxonomic name

The taxonomic name conforms to the syntax controls of the taxonomic classification system identified in subfield ‡2. Precede subfield ‡a by subfield ‡c, which indicates the taxonomic hierarchical category to which the name belongs. Repeat subfield ‡a for each taxonomic name associated with the item. Each combination is input in repeatable subfields ‡c and ‡a in taxonomic hierarchical order.

‡c Taxonomic category

The taxonomic category to which the name in subfield ‡a belongs. The terms used in this subfield are specified by the thesaurus identified in subfield ‡2. Subfield ‡c always precedes the data with which it is associated.

‡0 Authority record control number

Subfield ‡0 (zero) contains the system control number of the related authority record or a standard identifier such as an International Standard Name Identifier (ISNI). The control number or identifier is preceded by the appropriate MARC Organization code (for a related authority record) or the Standard Identifier source code (for a standard identifier scheme), enclosed in parentheses. See MARC Code List for Organizations (http://www.loc.gov/marc/organizations/orgshome.html) for a listing of organization codes and Standard Identifier Source Codes (http://www.loc.gov/standards/sourcelist/standard-identifier.html) for code systems for standard identifiers. Subfield ‡0 is repeatable for different control numbers or identifiers.

‡2 Source of taxonomic identification

The name or MARC code that identifies the source list from which the taxonomic identification was assigned. For the MARC code, see Taxonomic Classification Source Codes (http://www.loc.gov/standards/sourcelist/taxonomic.html).
