I blogged about the fantastic Pase Domesday project yesterday, which is an online reference tool to access data about people and places from the Domesday Book.
What I should have mentioned as well is what seems to not be available from Pase Domesday, which is all the detail of what customs and fees are owed by each manor and borough, and also what resources they had – for instance how many plough teams, how many acres of woodland etc. All of this fascinating content is available elsewhere though and can be downloaded from:
The Economic and Social Data Service
You should be able to access everything in MS Access from these downloads.
