While the letters of the Mozart family are presented in the Online-Edition, the music collection has been cataloged in the RISM (Répertoire International des Sources Musicales) database and published in a printed catalog (Carus 2021) in its historical order, as well. The project was part of the Digital Mozart Edition (DME), a collaboration between the International Mozarteum Foundation and the Packard Humanities Institute in Los Altos, California. The project director was Dr. Ulrich Leisinger, head of the DME, and the project manager was Dr. Eva Neumayr. She was supported by Dr. Armin Brinzing, director of the Bibliotheca Mozartiana; Dr. Lars Laubhold (2014 to early 2016); Dr. Tobias Appelt (until June 30, 2019); and Fabian Weidinger (until September 30, 2021).
In the future, the musical sources of the collections of both Wolfgang Amadeus Mozart’s sons will be digitized and made freely accessible in an internet portal, so that the condition formulated by Josephine Baroni-Cavalcabò for the transfer of the collection to the Dommusikverein und Mozarteum, namely “that this collection, existing independently; established by the son in honor of the father, will be preserved inseparably for all times according to his explicit […] will; and thus can be shown to friends who share the enthusiasm about this unsurpassed musical hero,” will finally be at least partially fulfilled.
