IMSLP attempts to create a virtual library containing all public domain musical scores, as well as scores from composers who are willing to share their music with the world without charge. It includes many older editions of composers’ complete works that are now in the public domain.

Classical Scores Library will contain 400,000 pages of classical scores from both in-copyright and public domain editions. The major composers output is represented, as well as many lesser known composers and works. The collection includes works spanning time periods from the Renaissance to the 21st century. Coverage of score types is comprehensive, with full scores, study scores, piano and vocal scores, and piano reductions.
