083  Additional Dewey Decimal Classification Number (R)

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

[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.]
