FIELD DEFINITION AND SCOPE

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.

GUIDELINES FOR APPLYING CONTENT DESIGNATORS

■ INDICATORS

First Indicator - Classification number validity
Whether field 763 contains a standard valid, standard invalid, optional valid, optional invalid, or obsolete classification number. A standard classification number is one from the standard part of the schedules or tables; it may be valid or invalid for use in a bibliographic or authority record. An optional classification number is one which is provided as an optional alternative to the standard part of the schedule or tables; it may be valid or invalid for use in a bibliographic or authority record. An obsolete classification number is one that had been used in an earlier edition, but has been relocated to another number or discontinued.
These values generally contain the same information for the classification number in an internal subarrangement or add table entry as the codes contained in 008/08 (Classification validity) and 008/09 (Standard or optional designation) do for the classification number in field 153 (Classification Number).
0 - Not a classification number entry
Does not contain a classification number. Although the field may contain classification numbers embedded in explanatory text, it is not considered a classification number entry and is assigned value 0. When value 0 is used, subfield $a is not present in the field.

■ SUBFIELD CODES

$a - Classification number-single number or beginning number of span
Single classification number or the beginning number of a span contained in an internal subarrangement entry. The classification number may be partial (such as digits to be added or a Cutter number) or be represented only by an indication of sequencing. Subfield $a is not used for classification numbers that may be embedded in the text of a note.

$c - Classification number-ending number of span
Ending number of a classification number span contained in an internal subarrangement entry. The classification number may be partial (such as digits to be added or a Cutter number) or be represented only by an indication of sequencing.

$p - Corresponding classification field
Field tag of the field in which the internal subarrangement data would appear if it were not part of an internal subarrangement. May be repeated for option notes to show that the note would appear in field 683 (Application Instruction Note) or in some other field if it were not an option.
Allows for an easier conversion from an internal subarrangement to an external table if desired. May also be used to highlight specific types of fields for display or printing. If it cannot be determined which field the data would fall into if it were not part of an internal subarrangement, this subfield may be omitted. If the data is a reference and can be recorded in field 253 or 453, the choice of which tag to use in subfield $p is made according to how the text reads, not how it might read if it were made into a tracing. For example, "do not use; class in" would be a 253 as it now appears. If the data could be recorded in either field 153 or 253/353 choose 153.

INPUT CONVENTIONS

Tables in classification schemes - If desired, an internal table in a classification scheme may be considered an external one and coded as such. Each entry in an internal subarrangement or add table is recorded in a separate 763 field (if coded as an external table, each is recorded in a separate 153 field in a separate record). The sequence number is assigned following the order of the subarrangement or table. Subfield $8 is always the first subfield in the field.
Punctuation - Input punctuation as data in field 763 for invalid or optional numbers, because it is not possible to indicate which portion of the number is invalid when one portion of a span is invalid.

SCHEME-SPECIFIC CONVENTIONS

Dewey Decimal Classification - For the Dewey Decimal Classification value 1 (standard valid classification number) in the first indicator position is used when field 763 contains more than one classification number taken from the DDC Manual.

In DDC, subfield $d is used for pattern numbers or spans when either a complete number or an incomplete number is added (concatenated). If digits are dropped from the beginning of the pattern number or span and only the remaining digits added, subfield $r must be present to specify the digits dropped.
Library of Congress Classification - If an internal table is more than four lines or applies to more than 10 records (numbers), it is coded as an external table, i.e. each number to be applied is in field 153 of a separate table record (coded as "b" in 008/06 (Kind of record). If it is desirable to display it as an internal table, the table identification in field 153 subfield $z of each table record contains the classification number (or beginning number of a span) where it will display. If more than one table is required (for more than one subarrangement), "/1", "/2" etc. is appended to the table identification. In the record for the number(s) where the internal table is to appear, field 763 subfield $z also includes that table identification. The use of field 763 distinguishes the table identification as one that displays internally; an external table is identified in field 762 in the record to which it applies.

When separate table records are created for each number in an internal table, and field 763 is used as a reference to that table, it is not necessary to sequence the fields using subfield $8.
