The Open Fields of England describes the open-field system of agriculture that operated in Medieval England before the establishment of present-day farms surrounded by hedges or walls. The volume encompasses a wide range of primary data not previously assembled, to which are added the resultsof new research based upon a fifty-year study of open-field remains and their related documents. The whole of England is examined, describing eight different kinds of field-system that have been identified, and relating them to their associated land-use and settlement. Details of field structure areexplained, such as the demesne, the lord's land, and the tenants' holdings, as well as tenurial arrangements and farming methods.Previous explanations of open-field origins and possible antecedents to medieval fields are discussed. Various types of archaeological and historical evidence relating to Saxon-period settlements and fields are presented, followed by the development of a new theory to explain the lay-out and plannednature of many field systems found in the central belt of England. Of particular interest is the Gazetteer, which is organized by historic counties. Each county has a summary of its fields, including tabulated data and sources for future research, touching on the demesne, yardland size, work-service, assarts, and physical remains of ridge and furrow. The Gazetteeracts as a national hand-list of field systems, opening the subject up to further research and essential to scholars of medieval agriculture.
