A survey written between 1377/80AD to 1382AD of all the tenants, (their lands and it's quality), and services due to the Bishop of Durham - at the time Thomas de Hatfield. It was written in Latin and onto parchment - but was incomplete by the death of Hatfield. It is similar to Boldon Book in that covers the customal services due - but has major differences. It covers areas that the Bishops of Durham acquired, such as the Evenwood barony and the Sadbergh wapentake. It does not cover Bedlingtonshire in detail, the Norhamshire lands and Crayke manor, (North Yorkshire), where the Bishops held land. It has been published - though in Latin.
