Instructions for applying tables, subarrangements, or additions to classification numbers.

$a - Classification number-single number or beginning number of span (R)

Used to amplify the explanatory text of the note.

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

$i - Explanatory text (R)

Explains the scope of the classification number. This subfield is repeated when other subfields intervene in the explanatory text.

$p - Corresponding classification field (R)

For optional instruction notes (first indicator is coded 2), this subfield contains the tag of the field in which the data would appear if it were not an option. This subfield allows for an easier conversion from an optional instruction to the standard instruction. If it cannot be determined which field the data would fall into if it were not part of an optional instruction, this subfield may be omitted. If the data is a reference and can be recorded in field 253 (Complex See Reference) or field 453 (Invalid Number Tracing), the choice of which tag to use is made according to how the text reads, not how it might read if it were made into a tracing.

$y - Table sequence number for internal subarrangement or add table (R)

$z - Table identification (R)

$5 - Institution to which field applies (R)

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

$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.
