Definition

Information about how a synthesized classification number or a portion of a synthesized classification number was built. Field 085 traces the different components of a synthesized number, showing the different portions of the number and where the add instructions are given. If a number was built using two or more instructions, a separate field 085 is given for each instruction.

Primary use for this field is for the Dewey Decimal Classification, which is based on the concept of number building. Field 085 is repeated each time an addition is made to the base number.

For the Dewey Decimal Classification the base number (subfield ǂb) is always given first, followed by the location of add instructions (subfields ǂa and ǂc). When there are multiple additions to a synthesized number, a cumulative base number (the number which resulted from the previous addition) is used in subfield ǂb of the following 085 field. This field includes instructions about how many zeros to add for standard subdivisions. In these cases, the zeros are recorded in subfield ǂf.

[The Dewey number in the 082 field, 346.0469516, means law providing for government control and regulation of biological resources for the sake of conserving them. The first 085 field shows that the number 346.04695 was built with 346.046 Law of government control and regulation of specific kinds of natural resources plus 95 from 333.95 Biological resources, following the instructions at 346.046. The second 085 field shows that the number 346.0469516 was built with 346.04695 plus 16 Conservation from the first add table under 333.7-333.9, as instructed under 333.7-333.9.]

[The first two 085 fields show how the Dewey number in the 082 field, 599.0994, was built. The first 085 field shows that 599.09 was built with 599 Mammals plus 09 Geographic treatment from Table 1 Standard subdivisions. The second 085 field shows that 599.0994 was built with 599.09 plus 94 Australia from Table 2 Areas, following instructions at 093-099 in Table 1. The second two 085 fields show how the Dewey number in the 083 field, 598.0994, was built.]

Subfields

ǂa Number where instructions are found - Single number or beginning number of span

Number (single number or beginning number of span) where instructions are found.

082	0	0	ǂ8 1 ǂa 346.0469516 ǂ2 22

ǂb Base number

Base classification number to which one or more other numbers are added. In many instances it may be the same as subfield ǂa. When two or more additions are used to build one number, the base number for the second and following 085 fields is the number resulting from the immediately preceding addition.
