Thank You Very Much Quantum, That is everything I need to go on. I have in the passed downloaded much sheet music and nothing is better for a quick fix. However with peticular repertoire and composers I really respect, I like having not only a selection of material but a well printed book version. This peticular book is just of great interest. Nocturne in A Flat is fresh repertoire of mine. I think the last print was in 1970. I have no idea if there would ever be a reprint but it appears to be well sought after.
Many Thanks,
Elbert
