About: Computer: A History of the Information Machine

Computer: A History of the Information Machine is a history of computing written by Martin Campbell-Kelly and first published in 1996. It follows the history of "information machines" from Charles Babbage's difference engine through Herman Hollerith's tabulating machines to the invention of the modern electronic digital computer. A revised 2nd edition published in 2004 included new material on the Internet and World Wide Web, while the updated 3rd edition published in 2013 includes contributions from historians Nathan Ensmenger and Jeffrey Yost. The 3rd edition extends the story to include recent phenomena such as social networking and revises the discussion of early history to reflect new insights from the literature.
