Welcome to the Petrucci Music Library! Our goal is to create a virtual library containing all public domain music scores and/or sheet music, as well as scores from composers who are willing to share their music with the world without charge.

eh....the site has been around for a while, but excellent site to find some scores.

Wished they had Stravinsky's stuff there though. :lol:
