International Music Library Score Project (IMLSP)
This project offers free downloading of 58, 000 scores which are in the public domain. Browse by genre or instrumentation. The site also includes information on music publishers and plate numbers and a listing of available commercial recordings.
As this project is based in Canada, it is based on Canadian copyright law, but it does include a rating system for US and EU law.
The three “V” mean it is free and down loadable in Canada / US / EU.
Please read the information on this database carefully before downloading any material.
