Definition

Classification number used for subject access. It is taken from Dewey Decimal Classification and Relative Index, the Abridged Dewey Decimal Classification and Relative Index, and electronic updates to either edition.

1st Indicator

Type of edition. Indicates the edition from which the Dewey Decimal classification is taken. Use subfield ǂ2 for the actual edition number.

083 0   ǂz 2 ǂa 4947 ǂ2 22
[For a book on tunnels in the Swiss Alps. The Dewey number 388.13 is used for interdisciplinary works on tunnels, but the number itself is broader, covering a variety of special road features. Consequently, geographic area notation cannot be added to the primary number in field 082. Field 083 contains the geographic area notation from Table 2 for the Swiss Alps.]
 
1

Abridged edition. The class number was taken from the abridged edition.

 
7

Subfields

 
ǂa Classification number

The additional classification number applied to the resource, which could be used for subject access in addition to the primary classification number assigned.

082 0 4 599.0994 ǂ2 22
083 0   598.0994 ǂ2 22
083 0   ǂz 2 ǂa 94 ǂ2 22
[For a book on Australian birds and mammals. The Dewey number 599 is used for works on mammals and for comprehensive works on birds and mammals. The rest of the primary number in field 082 consists of 09 Geographic treatment from Table 1 and 94 Australia from Table 2. There is no way to tell from this number whether the book contains information about birds or not. The Dewey number 598 in the first 083 field means birds, and the full number means birds in Australia. The second 083 field has the Table 2 area number for Australia; it is intended to help users seeking everything about Australia.]
ǂc Classification number--Ending number of span

Ending number of a number span when the beginning number of the span is contained in subfield ǂa.

ǂm Standard or optional designation

Designates whether the classification number contained in the field is from the standard or optional part of the schedules or tables of the scheme identified by the first indicator (Type of edition) and by subfield ǂ2 (Edition number). The following codes are used: a (standard) and b (optional).

Standard or optional designation: If subfield ǂm is present, only one subfield ǂa should be coded, unless the value in subfield ǂm applies to all numbers in repeated occurrences of subfield ǂa. Otherwise, the field is repeated.
