Nineteen shelf marks from the collections of the Music Department of the National Library of the Czech Republic have been digitized. The earliest of them comes from the last quarter of the 18th century. Most of them were copied in the 19th century. A larger group is formed by handwritten copies of compositions by František Xaver Brixi (shelf mark 59 R 1236, 59 R 1237, 59 R 1240, 59 R 1247, 59 R 1250). Other manuscripts comprise handwritten copies of excerpts from W. A. Mozart’s opera The Abduction from the Seraglio, the score of Adalbert Gyrowetz’s opera Federico e Adolfo, the score of Joseph Drechsler’s theatrical play with songs Der Diamant des Geisterkönigs, as well as handwritten copies of liturgical texts and religious songs. Some of the manuscripts come from the collection of MUDr. Ludvík Hornov.
