"Pointing to monastic management as a kind of workshop for the new administrative techniques used later by the centralized monarchies, Day of Reckoning is at once learned, intelligent, and original. Medievalists as well as those interested in the development of management in history should read this book with considerable interest and pleasure." (Alain Boureau, École des Hautes Études en Sciences Sociales) "Interesting and wide-ranging. . . . The book is well-structured, lucidly written, and based on considerable research in original sources." (Early Medieval Europe)
