Computer: A History of the Information Machine is a history of computing written by Martin Campbell-Kelly and William Aspray 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.

Reviews

According to Michael Mahoney's 1998 review in IEEE Annals of the History of Computing, Campbell-Kelly and Aspray's account is "a highly readable, broad-brush picture of the development of computing, or rather of the computer industry, from its beginning to the present" which "sets a new standard for the history of computing." In his review in Technology and Culture, Robert Seidel writes that "Computer is a readable and comprehensive history intended to acquaint novices with a growing historical literature as well as to provide an overview of that history from Charles Babbage through Bill Gates. The authors are well-known contributors to that literature. They have gone beyond it, however, in their interpretation, adding insights that can arise only from a synthetic view of the origins, development, and use of the computer."
