The tithe surveys of mid-nineteenth-century England and Wales marked a new departure in government-sponsored, cadastral surveying of the nation's land. The 11,800 large-scale, detailed maps which they comprise are recognised as one of the most important sets of manuscript historical sources used by historical geographers and economic, social and local historians as well as lawyers representing clients in property and rights of way disputes and county and local planning offices. Despite this much acknowledged value, historians are not well served with indexes, descriptive catalogues or indications of tithe map coverage. A first object of this book is to provide a standard work of reference which will be an essential research tool for users of tithe maps. The database has also been analysed to reveal the general cartographic characteristics of this internationally important government survey.
