Field definition and scope

Carrier type reflects the format of the storage medium and housing of a carrier in combination with the media type (which indicates the intermediation device required to view, play, run, etc., the content of a resource). Used as an alternative to or in addition to the coded expression of carrier type in field 007/01 (Specific material designation). Field 338 information enables indication of more specific carrier types and carrier types from various lists.

Multiple media types from the same source vocabulary or code list may be recorded in the same field in separate occurrences of subfield ‡a (Carrier type term) and subfield ‡b (Carrier type code). Terms from different source vocabularies are recorded in separate occurrences of the field.

Subfields

‡a - Carrier type term

‡b - Carrier type code

Code for the category of carrier used to convey the content of the resource.

‡2 - Source

MARC code that identifies the source of the number or code used to record the carrier type information. Code from: Genre/Form Code and Term Source Codes.

‡3 - Materials specified

Subfield ‡3 contains information that indicates the part of the described material to which the field applies.

‡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>\<field link type>

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).

The field link type is separated from preceding data by a reverse slash "\". It is a code indicating the reason for the link and it follows the link number or sequence number if present. The following one-character field link type code has been defined for use in subfield 8 in OCLC local holdings records: a - Action

Code a is used in a record 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 that relates to another 5XX field.
