While acknowledging that NACO catalogers are not supposed to use the 382 $v yet (at least in authority records), I still have a question on its link to RDA, if any. Is this subfield associated with RDA 7.21 (Medium of Performance of Musical Content) in some way? Or is it intended as a "MARC-only" thing? I didn't see any elaboration on a 382 field note while scanning discussion papers, proposals, and MARBI minutes. Details on the 382 field are here: <http://www.loc.gov/marc/authority/ad382.html> <http://www.loc.gov/marc/bibliographic/bd382.html> -- Mark K.
