Sheet Music Consortium

http://digital.library.ucla.edu/sheetmusic/

The Sheet Music Consortium is a group of libraries working toward the goal of building an open collection of digitized sheet music using the Open Archives Initiative:Protocol for Metadata Harvesting (OAI:PMH).

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. For technical details of the harvesting process and service, consult the Project Timeline and Technical Overview. Member institutions and data providers have chosen to catalog their sheet music in different ways, but a very large proportion of the original sheets in participating collections has been digitized, allowing users direct access to the music itself and — in many cases — covers and advertisements that offer evidence of the cultural context in which the songs were published.
