763 - Internal Subarrangement or Add Table Entry (R)
MARC 21 Classification - Concise
2007
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 to the record
to which it applies. In this case, the table which provides the arrangement for or
addition to the classification number or number span recorded in 153 is recorded in
subfield $z of this field.

Subfield Codes
$a - Classification number-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)
$h - Caption hierarchy (R)
Caption for each higher level of the caption hierarchy that precedes the caption
in subfield $j (Caption) that is associated with a classification

in some other field if it were not an option.
$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 must also be present to specify
the digits that are added.
$s - See reference (R)

subarrangement refers.
$x - Other classification number (R)
Classification numbers other than those that belong in one of the other defined
