The Cuckoo's Egg: Tracking a Spy Through the Maze of Computer Espionage

Agree with all posted before. Adding Clifford Stoll, Cuckoo's Egg; white it's not so much a history of computing as a personal history of a geek astronomer catching a hacker, it represents a lot of early computing culture, and I enjoyed it a lot.

"The Cuckoo's Egg: Tracking a Spy Through the Maze of Computer Espionage" by Clifford Stoll was a great read. The title gives away the premise of the book, but to think - it was all put into motion because of a $0.75 accounting discrepancy.
