The Internet has massively changed the way we identify ourselves, to the benefit and detriment of youth, argue Gillispie and Gackenbach. They explain how chat lines, role-playing games and other popular Internet pursuits can help foster imagination in formative minds, and they also broach the oft discussed vices associated with cybersex and online video games. The authors discuss ways clinicians and parents can help youth create disciplined patterns of Internet use. (800) 233-4830, http://www.wwnorton.com.
