The Domesday Book is a record of the survey conducted in England in 1086 by officials of William The Conqueror so as to assess taxes etc. The Domesday Book contains a survey of almost all the lands in England. The survey was made by commissioners, who collected the information in each district from a sworn jury consisting of sheriffs, lords of manors, presbyters, bailiffs, villeins - all the classes, in short, interested in the matter. The extent, tenure, value, and proprietorship of the land in each district, the state of culture, and in some cases the number of tenants, villeins, serfs, etc, were the matters chiefly recorded. The survey was completed within a year. Northumberland, Durham, Cumberland, and Westmoreland were not included in the survey, probably for the reason that William's authority was not then (in 1086) settled in those parts. The original Domesday Book consists of two volumes, one folio and one quarto. It has been republished a few times, a perfect facsimile of the original being published in 1861-1865.
