Field definition and scope

This field contains local control numbers that identify the holdings record or a related bibliographic record for which a separate holdings record is made. Numbers may include local system, accession, or serial control numbers. Each valid system control number with any related canceled or invalid system control numbers is contained in a separate 035 field.

‡z - Canceled or invalid control number

Subfield ‡z contains a canceled or invalid system control number that is associated with the valid control number contained in subfield ‡a.

Enter the local institution's MARC organization code (see MARC Code List for Organizations), in parentheses, before the canceled or invalid system control number. Do not enter a space between the symbol and the control number.

‡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).

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