MARC 21 fields 610-651


Fields 600-658 (with the exception of field 653 that is used for uncontrolled index terms) contain subject headings or access terms that provide additional access to a bibliographic record through a heading or term that is constructed according to established subject cataloging or thesaurus- building principles and guidelines. The standard list or authority file used is identified by the value in the second indicator position or by the MARC source code contained in subfield $2 that is used in conjunction with value 7.
The arabic number that precedes a subject access field in some displays is not carried in the MARC record. It may be generated based on the field tag. The dash ( -- ) that precedes a general subject subdivision is not carried in the MARC record; it may be generated based on the presence of subfields, $v, $x, $y, and $z.
