The 1279-80 hundred rolls are one of the most important sources for later thirteenth century England, yet this is the first comprehensive study of the inquiry which brought them into being. A Second Domesday will be an indispensable working tool for historians and is based on the latestknowledge of the returns. More of these are being discovered all the time and one of the aims of this book is to stimulate the recognition of other surviving texts. The book places the inquiry in its historical context, continental as well as English. This is followed by an examination of itspurpose and whether or not it was conceived deliberately as a second Domesday Book. Central to the study is a consideration of the geographical range of the inquiry, how it was conducted and the way in which the returns were compiled. The way in which the inquiry was used, by historians as well ascontemporaries, along with the introductory chapters will be particularly helpful to students. The book concludes with a description of all known returns, which, together with the appendices, are designed to assist future users.
