The BBC Domesday Project was a partnership between Acorn Computers, Philips, Logica, and the BBC to mark the 900th anniversary of the original Domesday Book, an 11th-century census of England. It has been cited as an example of digital obsolescence on account of the physical medium used for data storage.

Domesday Book is a manuscript record of the Great Survey of much of England and parts of Wales completed in 1086 at the behest of King William the Conqueror. The manuscript was originally known by the Latin name Liber de Wintonia, meaning "Book of Winchester", where it was originally kept in the royal treasury. The Anglo-Saxon Chronicle states that in 1085 the king sent his agents to survey every shire in England, to list his holdings and dues owed to him.
