It would be interesting to know if they plan to include information
omitted from the New Grove, that was available in the 5th Edition.
Citations in the New Grove say "See article in the 5th Edition," etc.,
obviously assuming that you will retain that edition as well.  Furthermore,
much information was omitted in the 5th Edition that had appeared, say, in
the 3rd Edition - bios and work lists of dozens of composers known mainly
for organ music, for instance.
