The National Library of Scotland acquires music through the legal deposit privilege, as well as through bequests, donations and purchases.
The music collections now include extensive British holdings, especially Scottish music. There is a wide selection of foreign music editions, special collections of early editions of Handel, Berlioz and Verdi, special collections of Scottish music collectors, and music sound recordings.
Music manuscripts are administered by Manuscript Collections.
