FIELD DEFINITION AND SCOPE
Single Dewey classification number or a 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.
