The making and publication of this database have been possible thanks to funding from the Swiss National Science Foundation and from the Fachhochschule Nordwestschweiz. We are grateful in particular to Thomas Drescher, Director of the Schola Cantorum Basiliensis, and to André Weishaupt, Head of Services, for their institutional support.

A special thanks goes to Marie Verstraete, former collaborator of the Motet Cycles Project, who substantially contributed to the conception and design of the database and to the first stages of its development. Hanna Marti, who joined the team in itinere, was instrumental in editing the data, as well as in the day-to-day problem solving which preceded the publication. We are also grateful to Jan Koláček, who technically implemented the database and patiently adapted it to our needs, and to Jan Geschke, of the IT Support team at the Schola, who assisted us in many ways during the project. Finally, we express our warm thanks to all the colleagues who accepted to act as beta-testers and provided invaluable feedback and suggestions.
