341 Accessibility Content

Field definition and scope:

Field 341 contains information about modes of access to the content of a resource, including its primary mode of access and alternative mode(s) of access.

Each occurrence of the field requires one subfield $a to record the mode of access for which an alternative mode is provided and one or more $b-$e subfields identifying the type of alternative access. Values for subfields $b-$e should be taken from the same controlled vocabulary.

Multiple values from the same source vocabulary may be recorded in the same field in separate occurrences of subfields. Terms from different source vocabularies are recorded in separate occurrences of the field.

Field 341 is repeatable.
