INPUT CONVENTIONS

Multiple content types from the same source vocabulary may be recorded in the same field in separate occurrences of subfield $a (Content type). Terms from separate source vocabularies must be recorded in separate fields. Each instance of field 336 must contain only terms in $a subfields or only codes in $b subfields.
