William of Malmesbury's Carolingian sources

In his great history of England, the Gesta regum Anglorum, completed in 1125, William of Malmesbury included digressions on continental affairs. One of these, on the Merovingian and Carolingian monarchs, provides an interesting study of William's historical method. His Frankish sources are difficult to identify, but we are helped by the survival of the late twelfth-century English MS. Oxford, Bodleian Library Lat. class d.39. This book contains, inter alia, a collection of chronicles and short pieces on Frankish history. We attempt to show that it was copied from a MS. made by or for William, and that his own notes were recopied into its margins. Moreover, it seems probable that he himself compiled the collection of chronicles in it. This discovery enables us to identify most of William's Frankish materials, to draw important conclusions about his manipulation of them, and so advance our knowledge of twelfth-century historiography generally.
