The music collections at Cambridge University Library play an important role in the preservation of musical heritage, both on a national and international level. From printed and manuscript music scores and texts on music to ephemera and concert programmes, archival materials documenting the life and work of composers, music scholars and performers, a huge variety and breadth of material has been collected over several centuries. We launch with a selection of important early lute music, digitised and described in collaboration with the Lute Society.
