Music Research Guide: Open Educational Resources

Project Gutenberg is a database containing books that are either free in the United States because their copyrights have expired, or are copyrighted works that the authors have given permission for them to be distributed freely, in non-commercial means. It also contains a variety of written and recorded music.

Harvested metadata about sheet music in participating collections is hosted by UCLA Digital Library Program, which provides an access service via this metadata to sheet music records at the host libraries. The project has been supported by the Institute of Museum and Library Services.

The Répertoire International des Sources Musicales (RISM) is an international, non-profit organization with the aim of comprehensively documenting extant musical sources anywhere in the world. Independent national working groups at libraries and archives in many countries worldwide catalog historical musical sources: music prints, music manuscripts, libretti, and theoretical writings about music. The results are edited and published by RISM.
