Auction house Christies is aiming to raise more than £1m from an auction of items promoted as "The Origins of Cyberspace: A Library on the History of Computing, Networking and Telecommunications".
The auction, ranging from early computer games to original letters from the "father of computing" Charles Babbage, consists of 250 lots covering 1,150 items.
Original Arpanet documents relating to the construction of the first pieces of the web, written by Vint Cerf and Bob Kahn, could fetch more than £1,500. A letter from Babbage on his counting machine could go for more than £8,000.
The auction will take place in New York on 23 February. More details can be found at:
