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 ‡b) is always given first, followed by the location of add instructions (subfields ‡a and ‡c). 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 ‡b 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 ‡f (Facet designator).

[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.]

‡8 Field link and sequence number

Data that identifies linked fields and may also propose a sequence for the linked fields. Subfield ‡8 may be repeated to link a field to more than one other group of fields. You are responsible for creating and maintaining the link. The system does not create or maintain these links. The structure and syntax of subfield ‡8 is:

      ‡8 [linking number].[sequence number]\[field link type]
085     ‡8 2.3\x ‡b 891.783 ‡z 3B ‡a 81 ‡c 89 ‡z 3B ‡w 81 ‡c 89 ‡y 1 ‡t 09 ‡u 891.78309
 

Subfield ‡8 has three parts:

The linking number is required. It occurs in subfield ‡8 in all fields to be linked (fields containing the same linking number are linked).

The sequence number is optional and preceded by a period ( . ). It is used to indicate the order in which the linked fields display (lower sequence numbers display before higher ones). If used, it must occur in all subfields ‡8 containing the same linking number.

The field link type is required and preceded by a reverse slash ( \ ). It is a code indicating the reason for the link and it follows the linking number (or sequence number, if present). Field link type is required except when subfield ‡8 is used to link and sequence 85x-87x holdings fields. These are the valid codes:

a (Action). Used to link one or more fields with another field to which the processing or reference actions relate. This code is typically used only when there is more than one 5xx field that relates to another 5xx field.

c (Constituent item). Used in a record for a collection or a single item consisting of identifiable constituent units, to link the fields relating to the constituent units. All other non-linked data elements in the record pertain to the collection or item as a whole.

p (Metadata provenance). Used in a record to link a field with another field containing information about provenance of the metadata recorded in the linked field.

r (Reproduction). Used in a record for a reproduction to identify fields linked because they contain information concerning only the reproduction. Other descriptive information in the record pertains to the original (with the exception of field 007, fixed field Form, and field 533).

x (General sequencing). Used in a record to make a link between fields to show a sequence between them. The sequence could be one that orders the pieces of a long field that has been broken up, indicates the relative importance of fields within the sequence, or is used for some other sequencing purpose. Use of the sequence number in subfield ‡8 is required when this code is used.

Printing

Field 085 does not print. Use field 092 to print Dewey numbers.
