We have worked in this research area for some 40 years now, and there are many people and organizations that we would like to thank for their kind assistance in supporting our research. 
We have been given much assistance at the Archives National in Parks, the Bibliotheque National, Archives at the Chateau Vincinnes, the regional archives in Macon, and local archives in Uxeau and surrounding communes.
Bernard Bezes and his colleagues at IGN, the Institut Geographique National, have provided us with much information, data, and access to their archives and resources.
Finally, to all of the many people of Burgundy who have allowed us access to their fields, answered our questions, and patently explained their world to us, and have invited us into their homes and lives, we express our profound appreciation.
