In MARC: Record as a structured description using field 337 subfield $a. If multiple terms are used, record each in a separate 337. If deemed useful for identification or selection, specify the part of the manifestation to which the term refers in 337 $3.

Additionally, for audio and video recordings: Record as an identifier using field 007 byte 00. For electronic resources with audio or video content, record a 007 with byte 00 value c and a second 007 with byte 00 value s or v as appropriate.
