306  Playing Time (NR)  (Variable Data Field)

Field definition and scope:

Field 306 contains a formatted numerical representation of the playing time of the item, e.g., the duration of a sound recording or the stated playing time of performance of printed or manuscript music.  The playing time is also recorded in natural language in a note (field 500 and/or 505) or, for sound recordings, videorecordings, etc., in field 300 (Physical Description).

If, for non-music sound recordings, the complete playing time is recorded in the physical description area (field 300, subfield $a) and the playing time of the parts are recorded in the contents note (field 505), field 306 should contain either the playing time of the whole or the playing time of the parts, whichever is deemed more useful.

The National level record requirement for this field is Optional.

Field 306 is NOT repeatable.
