The introduction provides a quick tour of cyberspace (on-line services, bulletin board systems, private systems, and networks) and activities (e-mail, public messaging systems, software exchange, electronic publishing, entertainment, chat, educational and research services, and commercial applications). Cavazos and Morin then take up electronic privacy issues including anonymity and both statutory and common law approaches to protecting private communications (featuring a discussion of Steve Jackson Games v. United States Secret Service); the virtual marketplace of electronic contracts and credit card transactions; copyright law in an uncharted new world; freedom of speech; adult material (digitized images, animated sequences, sexually explicit text, "hot chat"); and cyber-crimes.
