Our newest online subscription is to Classical Scores Library from Alexander Street Press. The current release includes 13,558 scores and 277,028 pages.

From the press release:

“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.
Content in the database includes in-copyright material from Boosey and Hawkes and selected material from the University Music Editions microfilm series.
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.
Further releases will include the entire catalog of UME, as well as manuscript material from the Barry S. Brook Center for Music Research, and many new editions from other in-copyright publishers.
All this is being done within a new interface that we expect users to find cleaner and easier to navigate, as well as a new platform under which we will publish all of our music databases, both live and in planning.”
