More Internet For Dummies by John R. Levine
This handbook goes beyond the options people identify as the Internet (such as email, the Web and newsgroups) and looks at lesser-known topics such as registering and building a Web site, using the Internet as a telephone or video-phone, and making a high-speed Internet connection. It also covers some of the oldest features on the Internet, like tele-netting and using the gopher system, and explores their current value.
