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
Classification Scheme Source Codes.
