083 - DEWEY DECIMAL CLASSIFICATION NUMBER (R)
A single Dewey classification number or a range of numbers associated with a 1XX heading in an established heading record or a subdivision record. The classification number is taken from 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. The hyphen (-) between the two class numbers in a range of numbers may be generated based on the presence of both subfields $a and $b; the parentheses that may enclose an explanatory term in subfield $c in an established heading record; the abbreviation T before the table in subfield $z; the dash (-) between the table number and the class number in subfields $z and $a; and the abbreviation dc before the edition number in subfield $2 may be system generated for display.
