Classical Scores Library contains 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.

Content includes 800 scores (approx. 25,000 pages) of in-copyright material from Boosey and Hawkes and selected material from the University Music Editions microfilm series. 49 composers' works are included in this release, including notable 20th-century composers such as Aaron Copland, Benjamin Britten, Igor Stravinsky, and Ned Rorem. This first release contains 16 full operas, 7 oratorios, over 50 string quartets, 27 symphonies, 60 concerti, and more.

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.

The database has been indexed to enable users to search on musically relevant fields, such as composer, work/opus number, key, genre, instrument, time period; as well as score-specific fields, such as score type, duration, editor, arranger, publisher. We hope that this will enable users to search, analyze, and research scores in a simple but powerful manner.

CSL has acquired the complete or collected works for these composers and will include these in future releases.
