Adam Clarke Bible Commentary

Nine months and twenty days - This was a considerable time; but they had much work to do, nor did they complete the work, as appears from Ch1 21:6; Ch1 27:24. William the Conqueror made a survey of all England, particularizing "how many hides or carucates the land is taxed at; whose it was in the time of his predecessor Edward; who the present owners and sub-tenants; what and how much arable land, meadow, pasture, and wood there is, how much in demesne, i.e., held and cultivated by the landowners; how much in tenantcy, and what number of ploughs it will keep; what mills and fisheries; how many sockmen, freemen, co-liberti, cotarii, bordarii, radmanni, radchenisters, villains, maid-servants, and bondmen, there are; how many hogs the woods would support; how many churches, priests, or parsons; what customary rents, prestations, and services, are to be paid and rendered out of the lands; what has been added to the manor; what has been withheld from it, and by whom; what land is waste, and what the whole was let for in the time of King Edward; and what the nett rent, and whether it was too dear rented, and whether it might be improved." This survey was begun in the year 1080, and was finished in the year 1086, six years having been employed in the work. This most important document is still preserved; it is in the Chapter House, Westminster, in two volumes, one in folio, on three hundred and eighty-two leaves of vellum. the other in quarto, on four hundred and fifty leaves; and is in as good preservation as it was seven hundred years ago. This work was much more difficult than that which was performed by Joab and his fellows. The work itself is known by the name Domesday Book.
