The set of digitised sheet music from the collections of the Music Department of the National Library of the Czech Republic has been augmented by another 57 shelf marks. The oldest manuscript digitised is a Dominican collection of texts for the Office, hymns and a part of the proper of the Mass for selected feast days of the liturgical year from the end of the 15th century. A large part of later items is represented by works by Jan Nepomuk Kaňka, partly preserved in an autograph. Other authors represented include e.g. F. X. Brixi, V. Maschek and B. D. Weber.
