Why was the Domesday Book called the Domesday Book?

The Domesday Book consisted of two volumes held in the Royal Treasury at Winchester in Hampshire, where it was known as The Book of Winchester. It formed a definitive source of information in the settling of court cases and was frequently consulted. Later it was transported to Westminster, where it acquired the jokey nickname 'Domesday Book' because its authority in legal terms was as absolute as God's judgment or 'doom' of a human soul when it left the human body and met its appointed destiny.
It was called the doomsday book as it means judgement day you couldn't escape it
