A historical study and translation inevitably owes much to a number of individual scholars who were kind enough to answer my inquiries or correct errors I might otherwise have made. While I cannot name them all, I would be remiss if I failed to mention some of those without whose support or assistance this project would have been a much more difficult undertaking, First, I should like to thank the librarians at Harvard University's Houghton Library for providing access to its manuscript collection. I would also like to thank librarians at the Institut de Recherche et d'Histoire des Textes at the Centre National de la Recherche Scientifique in Paris for supplying manuscripts of Odo's work in microfilm copies and for correcting at least one entry in the manuscript catalogues. Dr. Albert Houssiau, Bishop of Liège, also provided help with the manuscript tradition and directed me to Mr. Naedenoen's dissertation on Odo's Exposition on the Canon of the Mass, submitted to the University of Louvain. I should also like to thank Charles Dereine, whose work first brought Odo of Tournai to my attention. Despite a long illness, Dr. Dereine was kind enough to provide me with additional information on manuscripts at the abbey of Marchiennes.
Professors Kenneth Kitchell at Louisiana State University and Gerald Press at Hunter College read at least portions of the translation and offered suggestions or corrections. So too did Professor Ann Matter for the University of Pennsylvania Press. I am grateful for their comments and for those of other readers.
I must also thank the National Endowment for the Humanities, which provided me with a Travel to Collections Grant to support my research, and the Littauer Foundation, whose financial assistance helped bring this volume to press.
Lastly, let me thank my wife, Elizabeth, who listened patiently to the many frustrations that accompanied this project, and our daughter, Ariel, who is a visible reminder of the perfection that animates the religious quest. For whatever imperfections remain in this work, however, I am alone responsible.
