The purpose of this study was to identify the amounts and types of land affected by both parliamentary and non-parliamentary enclosure in the eighteenth and nineteenth centuries. The dataset represents a small portion of the data collected by the <i>National Enclosure Project</i> since 1972. It covers non-Parliamentary formal agreements in Dorset, Hampshire, East Sussex, West Sussex and Wiltshire; and Parliamentary enclosures in Hampshire and West Sussex. The database includes abstracts of all surviving formal agreements. The main topics are land type; acreages; landowners; commissioners.
