The set of thirty digitised music manuscripts from the National Library of the CR comes from the so-called Mozart Memorial, which was established in the National Library in 1837 as the very first Mozarteum in the world. It contains a representative selection of Mozart’s work, especially historically important copies and the first printed editions. Most of the volumes digitised in 2019 come from the turn of the 19th century; they contain handwritten copies of scores (mostly of Mozart’s concerts) and of the librettos of the operas La clemenza di Tito and Idomeneo.
