FIELD DEFINITION AND SCOPE

Single Dewey classification number or a number span associated with a 1XX heading in an established heading record or a subdivision record. Source of the classification number is the Dewey Decimal Classification and Relative Index; the Abridged Dewey Decimal Classification and Relative Index; and electronic updates to either edition. Through 1997, updates were issued in the DC& Dewey Decimal Classification Additions, Notes and Decisions.

Classification number(s) may be qualified by a descriptive term when the heading is represented in more than one place in the Dewey classification schedules. In a subdivision record, the field also contains the number of the table from which the classification number is taken. Each classification number or number span associated with a heading is contained in a separate 083 field. The second indicator values distinguish between content actually assigned by the Library of Congress and content assigned by an organization other than LC. The organization is identified in subfield $5.
