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. For more information, see Representation of DDC in MARC 21 Bibliographic Format: An Update at http://www.oclc.org/dewey/news/conferences/2009MARC21.ppt.
|‡a Number where instructions are found-single number or beginning number of span|
|‡b Base number||Base classification number to which one or more other numbers are added. In many instances it may be the same as subfield ‡a. 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.|
|‡c Classification number - Ending number of span||Ending number of a classification span under which an internal subarrangement or add instructions are found.|
|‡f Facet designator||Extra character(s) to be added to classification numbers that indicate facets.|
|‡r Root number|| |
Initial digits of the pattern number or span when these digits are not added. If this subfield is present, subfield ‡s or ‡t must also be present to specify the digits that are added.
|‡s Digits added from classification number in schedule or external table||Digits that have been added from a classification number in a schedule or external table to make up the synthesized number.|
|‡t Digits added from internal subarrangement or add table||Digits that have been added from an internal subarrangement or add table to make up the synthesized number.|
|‡u Number being analyzed||Repeated when the same 085 field is applicable to more than one number appearing in the same record.|
|‡v Number in internal subarrangement or add table where instructions are found||Number (single number or beginning number of span) in an internal subarrangement or add table under which add instructions are found.|
|‡w Table identification - Internal subarrangement or add table||Classification number (single number or beginning number of span) under which an internal subarrangement or add table is found.|
|‡y Table sequence number for internal subarrangement or add table||Sequence number or other identifier for an internal classification subarrangement or add table. If the first or only add table found at a classification number is the number 1, and succeeding integers are used for any following add tables found at that number.|
|‡z Table identification||Identifies the table used in building a number. For a classification number span, subfield ‡z is given only once, before the first number.|
|‡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: |
Note: Subfield ‡8 is defined differently in field 852, where it is used to sequence related holdings records.
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.
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 (Physical Description fixed field), fixed field Form, field 245 subfield ‡h (Title Statement / Medium), and field 533 (Reproduction Note)).
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.
