MARC 21 Concise Format for Classification Data: 761: Add or Divide Like Instructions (Network Development and MARC Standards Office, Library of Congress)

This is an ARCHIVED VERSION of the 2009/2010 electronic edition of the MARC 21 Concise Formats. Please see loc.gov/marc/concise/ for the most up-to-date version of the electronic MARC 21 Concise Formats.

Information necessary to construct a classification number by adding numbers from other parts of a schedule or from a table or by basing it on numbers defined in other parts of a schedule (dividing it the way numbers in other parts of the schedule are divided).

$a - Number where instructions are found-single number or beginning number of span (R)

$b - Base number (NR)

$c - Classification number-ending number of span (R)

$d - Divided like number (R)

$e - Example class number (R)

$f - Facet designator (R)

$i - Explanatory text (R)

$n - Negative example class number (R)

Example of the incorrect classification number for the topic used to illustrate the add or divide like instruction.

$r - Root number (R)

Initial digits of the pattern number or span when these digits are not added. If this subfield is present, subfield $d (Divided like number) must also be present to specify the digits that are added.

$x - Other classification number (R)

Classification numbers other than those that belong in one of the other defined subfields. If the number is part of a classification number span, subfield $c is used for the ending number in the span.

$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 (NR)

See the description of this subfield in Appendix A: Control Subfields.
