Levy describes the people, the machines, and the events that defined the Hacker Culture and the Hacker Ethic, from the early mainframe hackers at MIT, to the self-made hardware hackers and game hackers. The book saw an edition with a new afterword (entitled "Afterword: Ten Years After") by the author in 1994. In 2010, a 25th anniversary edition with updated material was published by O'Reilly.
