083 - Dewey Decimal Classification Number (R)

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.

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.
