Field definition and scope

This field contains a standard number or code published on an item, that is copied from subfield ‡a of field 024 (Other Standard Identifier) of the MARC bibliographic record that represents the description of the item for which a separate holdings record is created. It may also contain any additional codes or a canceled/invalid code from subfields ‡d or ‡z of field 024 in the bibliographic record. The type of standard number or code is identified in the first indicator position or in subfield ‡2 (Source of number or code).

Additional information and description of the use of field 024 (Other Standard Identifier) is in OCLC Bibliographic Formats and Standards.

Guidelines for applying content designations

Indicators

First Indicator - Type of standard number or code

The first indicator position contains a value that indicates the type of standard code in the field.

0 - International Standard Resourcing Code (ISRC)

1 - Universal Product Code (UPC)

2 - International Standard Music Number (ISMN)

3 - International Article Number (EAN)

4 - Serial Item and Contribution Identifier (SICI)

7 - Source specified in subfield ‡2

8 - Unspecified type of standard number or code

Second Indicator - Undefined

The second indicator position is a value that indicates whether there is a difference between a scanned number or code and the same number or code in eye-readable form.

blank - No information provided

Value blank indicates that no information is provided as to whether the number or code in the field appears in the same form in both scanned and eye-readable form. It is also used when the eye-readable number or code does not appear in a form adequate for scanning, thus the aspect of difference does not apply.

0 - No difference

Value 0 indicates that the scanned number or code is the same as the number or code in eye-readable form.

1 - Difference

Value 1 indicates that the scanned and eye-readable versions of a number or code differ.

Subfields

‡a - Standard number or code

Subfield ‡a contains the standard number or code.

337          Audio ‡2 marcmedia

‡c - Terms of availability

Subfield ‡c contains the price or a brief statement of availability and any parenthetical qualifying information about availability.

024    2      M571100511  ‡c $20.00

‡d - Additional codes following the standard number or code

Subfield ‡d contains any optional digits carried to the right of the number or code, such as digits provided to identify price, title, or issue information

024    3      9780449906200  ‡d 51000

‡q - Qualifying information

A brief statement of qualifying information concerning the item associated with a number being recorded in subfield ‡a or subfield ‡z.

‡z - Canceled/invalid standard number or code

Subfield ‡z contains any canceled and/or invalid standard numbers or codes. If a valid number or code of the same type is not known, subfield ‡z may appear alone in field 024.

024    1      ‡z 5539143515

‡2 - Source of number or code

Subfield ‡2 contains a MARC code that identifies the source of the number or code. It is used only when the first indicator contains value 7 (Source specified in subfield ‡2). The source of the code is Standard Identifier Source Codes that is maintained by the Library of Congress.

‡8 - Field link and sequence number

Subfield ‡8 contains 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.

The structure and syntax for the field link and sequence number subfield is: ‡8<linking number>.<sequence number>

The linking number is the first data element in the subfield and required if the subfield is used. It is a variable-length whole number that occurs in subfield ‡8 in all fields that are to be linked. Fields with the same linking number are considered linked. A linking number of "0" (zero) is not used in this field.

The sequence number is separated from the linking number by a period "." and may be optional. It is a variable-length whole number that may be used to indicate the relative order for display of the linked fields (lower sequence numbers displaying before higher ones). If it is used it must occur in all ‡8 subfields containing the same linking number.

Subfield ‡8 is always the first subfield in the field when it is used.
