This book offered the first comprehensive study of the enclosure mapping of England and Wales. Enclosure maps are fundamental sources of evidence in many types of historical inquiries. Although modern historians tend to view these large-scale maps essentially as sources of data on past economies and societies, this book argues that enclosure maps had a much more active role at the time they were compiled. Seen from this perspective of their contemporary society, enclosure maps are not simply antiquarian curiosities, cultural artefacts, or useful sources for historians but instruments of land reorganisation and control which both reflected and consolidated the power of those who commissioned them. The book is accompanied by a fully searchable, descriptive and analytical web catalogue of all parliamentary and non-parliamentary enclosure maps extant in public archives and libraries and offers an essential research tool for economic, social and local historians and for geographers, lawyers and planners.
