"The Cyberspace Lexicon" was a hybrid encyclopedia/dictionary published in 1994. Though outdated today, it still serves as a look back into what state-of-the-art technology was like in the early 90s. There is a lot of emphasis on "hypermedia", "CD-ROM", and CD-based video game systems. There is also a good entry on "cyberpunk" and "anime", along with an early mention of HDTV. You'll get a kick out of the entry on "cybersex". All in all, it is a good read if you're into the history of computer technology.
