FIELD DEFINITION AND SCOPE
Information that identifies the authoritative classification
scheme used to formulate the number caption in field 153
(Classification Number).
Includes the edition that contains the classification
number(s) and term(s) in the record. It also may indicate the
edition title, date, and language of a particular version of the
classification scheme. If a library creates its own record for a
classification number maintained by another classification
source, the classification scheme on which it is based is
specified in field 084 and the library creating the record is
identified in field 040 (Record Source).

■ SUBFIELD CODES
$a - Classification scheme
code
Variable-length alphabetic MARC code
that identifies the classification scheme used to formulate the
classification number and caption in field 153 (Classification
Number). The code is based on the general classification scheme
used without regard to the particular edition or adaptation of
the scheme. A classification number or span that has been adapted
in some way from the information in the authoritative
classification scheme is coded for the scheme in this subfield
and the MARC code or name of the library that made the adaptation
is contained in field 040 (Record Source). The source of the
classification scheme code is

Conventions.
