An index term describing the occupation (including an avocation) reflected in the contents of the described materials. Do not use field 656 to list the occupations of the creators of the described materials, unless those occupations are significantly reflected in the records themselves.
|Undefined. The 1st indicator position is undefined and contains a blank ( ).|
|Source of term. The source of the index term is contained in subfield ‡2.|
|‡a Occupation|| |
A term specifying the occupation reflected in the contents of the described material.
|‡k Form|| |
The form of the material. Distinguish form by an examination of the physical character, by the order of information within the item or by the subject of the intellectual content (e.g., daybooks, diaries, directories, journals, memoranda, questionnaires, syllabi or time sheets).
|‡v Form subdivision||A specific kind or genre of material defined by the thesaurus being used. Use only when a form subject subdivision is added to an index term for occupation. Use subfield ‡v also for form terms when they function as indicated above. Use subfield ‡x if the terms function as general subdivisions. A form subdivision in subfield ‡v is generally the last subfield in the field. Repeat subfield ‡v if you use more than one form subdivision.|
|‡x General subdivision|| |
A subject subdivision that is not more appropriately contained in subfield ‡v, ‡y or ‡z. Use subfield ‡x only when a general topical subdivision is added to a term.
|‡y Chronological subdivision|| |
A subject subdivision that represents a period of time. Use only when a chronological subject subdivision is added to a term.
|‡z Geographical subdivision|| |
A geographic subject subdivision. Use only when a geographic subject subdivision is added to a main term.
|‡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 term|| |
A MARC code that identifies the source list from which the index term was assigned. Use only when the 2nd indicator value is 7. See MARC Code Lists for Relators, Sources, Descriptive Conventions ( http://www.loc.gov/marc/relators/relahome.html).
|‡3 Materials specified||The part of the described materials to which the field applies.|
|Field 656 prints as a heading and a tracing. Subfields ‡2 and ‡3 do not print. In both the heading and tracing paragraphs, the print program supplies the display constant Occupation: before the subfield ‡a data. Do not enter Occupation: in field 656. In the tracing position, the display constant prints after the appropriate Arabic numeral. The print program supplies a period after the last printing subfield unless final punctuation (. ! ?) is present.|
