While the material presented in this study was formed by consulting hundreds of published sources and archival material, the discovery and collation of this material would not have been possible without the kind help of several people. This includes personal communication with Robert de Bree, Elsa Frank, Lucas van Helsdingen, Samantha Owens, Jérémie Papasergio, Amy Power, and Nele Vertommen.
I must also thank the archives and libraries which were of great assistance to this project, particularly with consulting scores and other primary sources. This includes Martie Severt of the Bibliotheek van het Koninklijk Conservatorium, the Brabants Historisch Informatie Centrum, the British Library, Imogen Conroy of the Durham Cathedral Library, the Haags Gemeentearchief, Geeske Bisschop of the Koninklijke Verzamelingen, Åsa Sjöblom of the Lunds Universitetsbibliotek, Paula Quint of the Nederlands Muziek Instituut, the Stadsarchief Amsterdam, Annika Bostelmann of the Universitätsbibliothek Rostock, and the Zeeuws Archief. I am grateful to Stichting De Zaaier, who provided me with a grant for to travel to these archives and analyse details in the scores first-hand, rather than through scans.
Thank you to Michael Wayne for your diligent proofreading and guidance. Your support and encouragement kept me enthusiastic throughout the entire research process.
Two essential people who provided advice and feedback were Bert Mooiman and Bart van Oort. Without these two, this research would not have been possible!
