Books

The most important of his books are:

• Normandy before 1066 (London and New York, Longmans, 1982)
• A Bibliography of Domesday Book (Woodbridge, The Boydell Press, 1986)
• William the Conqueror (George Philip, 1989; reprinted, Tempus, 2001,2004)
• Regesta Regum Anglo-Normannorum: The Acta of William I, 1066–1087 (Oxford, Clarendon Press, 1998)
• The Normans and Empire (Oxford, Oxford University Press, 2013)
• William the Conqueror (London and New Haven, Yale University Press, 2016). Translated into French as Guillaume le Conquérant (Paris, Flammarion, 2019)
• La Tapisserie de Bayeux (Paris: Citadelles & Mazenod, 2019). Co-authored with Xavier Barral i Altet).

The Normans and Empire argues for a new analytical framework for the expansion of the Normans in Western Europe and for the experience of the British Isles. William the Conqueror (Guillaume le Conquérant) proposes a radical revision of the life of William the Conqueror.

All of his books are based on extensive researches in the archives and libraries in France and Normandy that have uncovered a lot of new or inadequately known material, some of it published in Regum Anglo-Normannorum: The Acta of William I. He retains an interest in the interpretation of charters as literary sources and is currently working on further innovative approaches to the history of northern Europe during the period from the tenth to the thirteenth century. A Festschrift has been published in his honour:

• Normandy and its Neighbours, 900-1250: Essays for David Bates, ed. David Crouch and Kathleen Thompson (Turnhout, Brepols, 2011).
