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. Through 1997, updates were issued in DC& Dewey Decimal Classification Additions, Notes and Decisions. | ||||||||||||||||
1st Indicator | Type of edition. The classification.number is from the full or the abridged edition of the classification schedules. Use subfield ‡2 for the actual edition number. | ||||||||||||||||

| ‡a 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.
| ||||||||||||||||
| ‡c Classification number - Ending number of span | Ending number of a number span when the beginning number of the span is contained in subfield ‡a. | ||||||||||||||||
| ‡m 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 ‡2 (Edition number). The following codes are used: a (standard) and b (optional). Standard or optional designation: If subfield ‡m is present, only one subfield ‡a should be coded, unless the value in subfield ‡m applies to all numbers in repeated occurrences of subfield ‡a. Otherwise, the field is repeated.
| ||||||||||||||||
| ‡q Assigning agency | The MARC organization code of the institution that assigned the classification number. See MARC Code List for Organizations ( http://www.loc.gov/marc/organizations/). | ||||||||||||||||
| ‡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 | Number of the table from which the classification number in a subdivision record is taken. Subfield ‡z always precedes the associated subfield ‡a in the field. | ||||||||||||||||
| ‡2 Edition number | The edition 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. | |||||||||||||||||
