Web Sources for Historical Sheet Music
In the business of putting on historical events, with appropriate music, one frequently encounters the need to find appropriate sheet music. Further, when one has been doing historical events for many years, one can get a bit tired of the same tunes all the time, and want to dig up something new--that everyone hasn't heard yet.
Fortunately, there seem to be a growing collection of sites on the web that can be tapped for historical sheet music. Of course, with copyright laws being what they are, you aren't going to find much past 1920, but if your interests lie in the Victorian or Ragtime eras (and occasionally earlier) there's some good stuff out there free of charge.
Here are the ones I know about. If you know some more, please add them via "comments".
