The original Latin manuscript of the Red Book has been lost but a transcription made by the antiquary William Thomas before 1738 survives. A version based on Thomas' transcription was published by Marjory Hollings of the Worcestershire Historical Society in 1934.[5][6]
A Doctor of Philosophy thesis by Emma Day in 2011 reviewed the numbers of free tenants and lower classes of peasants (villeins) recorded in the Red Book. Day found that 41% of the peasants in the manors of Kempsey, Bredon, Northwick and Wick noted in the Red Book were free tenants, who generally paid money rents rather than carrying out labour for their lords. This was a significant increase from the situation in Domesday where there were no freemen and only Northwick had recorded having radmen, a similar status to freemen. This was possibly as a result of Giffard's widespread granting of manumission to peasants and granting of leases on freer terms, because of a general surplus of labour at the time.[7]
