153 - Classification Number (NR)


MARC 21 Classification - Full
October 2008

Classification numbers that are constructed according to the classification scheme that is identified in field 084 (Classification Scheme and Edition). This field may contain a single classification number (008/07, Type of number, code a) or a span of classification numbers (008/07, code b or c) from a schedule (008/06, Kind of record, code a) or from a table (008/06, code b) and its associated caption (subfield $j) and caption hierarchy (subfields $h and $k). The subject context of the classification number is indicated by the preceding hierarchy captions contained in repeatable subfields $h and $k. (Field 153 must contain at least one subfield $a and one subfield $j.)

Subfield Codes
$a - Classification number--single number or beginning number of span (R)
$c - Classification number--ending number of span (R)
$e - Classification number hierarchy--single number or beginning number of span (R)
$f - Classification number hierarchy--ending number of span (R)
$h - Caption hierarchy (R)
Caption for each higher level of the caption hierarchy that precedes the caption for a classification number or span that is contained in subfield $j (Caption). The caption at the highest level is recorded in the first subfield $h. The caption at each successive level is recorded in sequence in separate subfields $h up to and including the level that precedes the caption contained in subfield $j. Captions for all levels of the hierarchy are recorded in the field. If the caption in subfield $j is the highest level of the hierarchy, subfield $h is not used. (However, some systems may wish to omit some levels of the hierarchy for display purposes.) A caption hierarchy for classification numbers in a summary number span in the Dewey Decimal Classification is contained in subfield $k (Summary number span caption hierarchy).
$j - Caption (NR)
Lowest caption in the caption hierarchy for a classification number or span.
$k - Summary number span caption hierarchy (R)
Caption at a level higher than the last for a summary number span when the classification scheme identified in field 084 (Classification Scheme and Edition) is the Dewey Decimal Classification. Caption hierarchies for single classification numbers, defined numbers spans, or other types of summary number spans are contained in subfield $h. The last caption in the caption hierarchy for a summary number span in field 153 (008/07, Type of number, code c for summary number span) is recorded in subfield $j.
$y - Table sequence number for internal subarrangement or add table (R)
$z - Table identification (R)
$6 - Linkage (NR)
See the description of this subfield in Appendix A: Control Subfields.
$8 - Field link and sequence number (R)
See the description of this subfield in Appendix A: Control Subfields.
