763 Internal Subarrangement or Add Table Entry

Field definition and scope:

Field 763 contains one entry in an internal classification subarrangement or add table. The entry may consist of a classification number and its associated caption, a note, or a see reference. A classification number that is part of an external table is recorded in field 153 (Classification Number) with the table identification recorded in subfield $z (Table identification) of that field. An internal table may also be coded as an external one and identified in subfield $z of field 153 of the record to which it applies.

Field 763 is repeatable.
