Definition

A term indicating the form, genre and/or physical characteristics of the materials being described. Genre terms for textual materials designate specific kinds of materials distinguished by the style or technique of their intellectual content (e.g., biographies, catechisms, essays, hymns or reviews).

 

Form and physical characteristic terms designate functionally and historically specific kinds of materials. Distinguish terms 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).

Use field 655 for terms constructed from a faceted vocabulary. For each term in the field, give an identification as to the facet/hierarchy from the thesaurus used. In addition, give an identification as to which term is the focus term of the expression.

1st Indicator

Type of heading. The type of heading in the field.
 
blank character Basic. The genre/form data is recorded in a single occurrence of subfield ‡a.
 
Faceted. Each genre/form term is recorded in a separate subfield ‡a or subfield ‡b. A subfield ‡c precedes each term in subfields ‡a and ‡b. Subfield ‡c denotes the facet/hierarchy of each term in a particular thesaurus.

2nd Indicator

Thesaurus. The thesaurus or subject heading system used in constructing the genre or form term.

Note: The previous practice for indicating the source of a genre heading was to use 2nd indicator value 7 (Source specified in subfield ‡2) and identify the MARC code for the source list in subfield ‡2. With the new practice, in addition to value 7, specific thesauri are now identified with 2nd indicator values. Users may use either the new or the previous practice to indicate the source of genre headings. Both are still valid.

 
Library of Congress subject heading. The formulation of the genre or form term conforms to the Library of Congress Subject Headings (LCSH).
 
1 LC subject heading for children's literature. The formulation of the genre or form term conforms to the "AC Subject Headings" section of Library of Congress Subject Headings.
 
2 Medical subject heading. The formulation of the genre or form term conforms to the National Library of Medicine (NLM) authority files.
 
3 National Agricultural Library subject authority file. The formulation of the genre or form term conforms to the National Agricultural Library (NAL) subject authority file.
 
4 Source not specified. The formulation of the genre or form term conforms to a controlled list, but the source cannot be specified by one of the thesaurus or subject heading systems covered by the other 2nd indicator values or by a code for a specific subject heading list in subfield ‡2.
 
5 Canadian subject heading. The formulation of the genre or form term conforms to the Canadian Subject Headings.
 
6 Répertoire de vedettes-matière. The formulation of the genre or form term conforms to the Répertoire de vedettes-matière maintained by the Bibliothèque de l'Université de Laval.
 
7 Source is specified in subfield ‡2 . Genre or form terms based on other subject authorities (i.e., on authorities other than those listed here). Identify the source in subfield ‡2.

Subfields

 
‡a Genre/form   For basic headings, subfield ‡a consists of all form, genre and physical characteristics data when the 1st indicator value is blank character . For faceted headings, subfield ‡a consists of the focus term when the 1st indicator value is . A focus term is the concrete thing forming the basis of expression.
655    7 Gampi fibers (Paper) ‡z Japan ‡y 1955 . ‡2 rbpap
655    7 Medical novels. ‡2 gsafd
‡b Non-focus term   A term other than that considered the focus in the faceted heading. Use with 1st indicator value .
655 7 ‡c d ‡b Black ‡c f ‡b Hmong ‡c m ‡b cotton ‡c k ‡b courtship ‡c t ‡a balls. ‡2 aat
[Heading: Black Hmong cotton courtship balls] 
‡c Facet/hierarchy designation   A designation identifying the facet/hierarchy designation for each term found in subfields ‡a and ‡b. Use with 1st indicator value . The designations and their associated facets/hierarchies are found in the thesaurus identified in subfield ‡2. Data in subfield ‡c always precedes the data to which it is associated.
655 7 ‡c k ‡b Laminated ‡c m ‡b marblewood ‡c v ‡a bust. ‡2 aat
[Heading: Laminated marblewood bust] 
‡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 a genre/form term. 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 topical subdivision is added to a genre/form term with a 1st indicator value of blank character .
655    7 Dictionaries ‡x French ‡y 18th century. ‡2 rbgenr
‡y Chronological subdivision  

A subject subdivision that represents a period of time. Use only when a chronological subject subdivision is added to a term.

655    7 Competition drawings ‡y 1984. ‡2 rbgenr
‡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 Genre/Form Code and Term Source Codes ( http://www.loc.gov/standards/sourcelist/genre-form.html).

‡3 Materials specified   The part of the described materials to which the field applies.

‡5 Institution to which field applies   A code of the institution or organization that holds the copy to which the field applies. Use for notes that do not apply to the universal description of the item. See MARC Code List for Organizations ( http://www.loc.gov/marc/organizations/orgshome.html) or Symbols and Interlibrary Loan Policies in Canada

Printing

Field 655 prints as a heading and a tracing. Subfields ‡c, ‡2, ‡3 and ‡5 do not print. In both the heading and tracing paragraphs, the print program supplies the display constant Genre: before the subfield ‡a data. Do not enter Genre: in field 655. 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.
