I am teaching a course on Film Music, and I've read of original scores to silent films by Walter Cleveland Simon. Because these were written and published before 1923, I believe they are in the public domain. However, I can't find sheet music to borrow, purchase, or download from anywhere. Does anyone have any information on where I might find sheet music for a few of these to use as examples in my course? Originals would be really awesome, but a copy or scan would suffice.
