I have noticed that some recent CDs include a catalog number for the
works of Villa-Lobos.  They are designated by a "W." but I can't find
any info relating to this catalog numbering system.  The New Grove lists
"S.  Wright: 'Villa-Lobos: the Formation of his Style' Soundings (1979-80)"
in the bibliography.  My guess is that this may be the same person who
put together the thematic catalog.  Can anyone elucidate?
