Subfields | |||||
| ‡a Taxonomic name | The taxonomic name conforms to the syntax controls of the taxonomic classification system identified in subfield ‡2. Repeat subfield ‡a for each taxonomic name associated with the item. Precede subfield ‡a by subfield ‡c, which indicates the taxonomic hierarchical category to which the name belongs. Each combination is input in repeatable ‡c and ‡a subfields 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. | ||||
| ‡d Common or alternative name | The common or alternative name to which the name in subfield ‡a belongs. Subfield ‡d may refer to one or multiple occurrences of subfield ‡a. | ||||
| ‡x Nonpublic note | A note pertaining to the taxonomic identification of the item that is in a form not adequate for public display. | ||||
| ‡z Public note | A note pertaining to the taxonomic identification of the item that is in a form adequate for public display. | ||||
| ‡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. Do not input subfield ‡0 in master records, instead use the control headings function. Local authority identifiers may be entered in subfield ‡0 locally, but should not be added to master records in WorldCat. | ||||
| ‡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 MARC Code Lists for Relators, Sources, Descriptive Conventions ( http://www.loc.gov/marc/relators/relahome.html).
