Seems to be missing, but I notice that at least some of it is here ? -- daten.digitale-sammlungen.de/~db/bsb00006456/images/ Eric 23:37, 9 March 2009 (EDT) (that has half the etudes, daten.digitale-sammlungen.de/~db/bsb00006457/images/ has the first half Eric 23:49, 9 March 2009 (EDT) )
I have a copy of a piece called On Wings of Song (Auf Flugeln des Gesanges) - it has the same notes as op. 67, La Vallée d'amour, which is posted on this site.
On Wikipedia.org, it says that op.67 is On Wings of Song, and has no mention of La Vallée d'amour. Since the notes are the same, is it worth putting in a second title, or should I even digitize my copy?
