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.
