IMSLP, the International Music Score Library Project, is also called the Petrucci Music Library. It is a free library of classical music run by volunteers, holding the sheet music, the parts, the arrangements and the recordings of works whose copyright has lapsed, together with what its pages say about each composer. It reviews the copyright of every score for Canada, the United States and the European Union separately, and publishes its pages under CC BY-SA 4.0.
This server connects a chat client to that library. Y
