I'm sure most of posters here know about the site, so this is for those that don't. If you're looking for any music sheet, you can find it on http://www.pianofiles.com.

The way it works, is you sign up, and enter the names of the sheets that you own in digital form. You can then look at other people's accounts and e-mail them asking for their sheets that you want.

It's all free, and so far all my requests were honored within a day or two, and for some pretty rare pieces.

I don't know if I'm violating forum rules by posting a link to that site, but personally I'm tired of online stores charging up to $20 for a single piece. Even $5.00 on musicnotes is silly, since you can only print the music once.
