William the Conqueror had a considerable interest in the property holdings of his subjects, and around Christmas 1085 he decided to commission a great survey to discover just what resources were out among the boroughs and manors of England. The massive document that came out of this lengthy process was the Domesday Book. It has fascinated historians for centuries, and recently The UK National Archives created this online guide to the work. Visitors can take a look through the book via interactive features such as “Discovery Domesday”, which provides a bit of background on the work, complete with images from its pages. Additionally, the “World of Domesday” feature provides some contextual background for understanding what life was like for the people of 11th century England. Visitors can search across the Domesday Book in its entirety by place name, person, or other keyword.
