We are grateful to the Fachhochschule Nordwestschweiz for its institutional support, and in particular to Thomas Drescher, Director of the Schola Cantorum Basiliensis, to Martin Kirnbauer, Head of the Research department, to André Weishaupt, Head of Services, as well as to the IT Support team at the Academy of Music FHNW. For technical assistance, we are especially grateful to Jürgen Enge, Head of the Center for Digital Matter at the Academy of Art and Design FHNW, for helping us in setting up and maintaining the web server.

The collaboration with the Veneranda Fabbrica del Duomo di Milano has been fundamental during the whole project: we express our heartfelt gratitude to Mons. Gianantonio Borgonovo, Head of Cultural affairs and Archpriest of the Duomo, and to the archivist, Maddalena Peschiera, with her team.

Thanks also to Thomas Schmidt and Rob C. Wegman for generously sharing research material, and to Cory McKay for his consulting and for sharing the results of computational analysis of anonymous works.
