Soon, mid-April to mid-May, I visit Rome, Florence, Venice, Vienna and Prague.

I'm a professional musician and would much rather see original music manuscripts than art. However, the national libraries and music departments of the museums where the manuscripts of the era I'm interested in are housed, are reluctant (read, will not) make them available to the general public unless the viewers are researchers. My days of formal research are long over, and countless emails and phone calls to many institutions will not move them. They also seem very understaffed, especially in Italy.

Now I'm on a mission to find where people may have accidentally come across some scores, in particular, vocal music by Mozart, Beethoven, Schubert, Schumann and other composers from around the late 1700's to the first half of the 1800's. I'm not so interested in finding medieval, renaissance or baroque scores - these seem to be quite prevalent and I've studied many.

e.g. The Lobkowicz Palace in Prague has a music archive holding some exciting works which I'm looking forward to visiting, but I was wondering if any Fodorites have discovered some treasures on public display in any of the cities I'm visiting.

Thank you for reading this rather specialised question.
