THIS BOOK HAS TAKEN A CAST OF THOUSANDS. I BEGAN WRITING IT A decade ago, in 1993. As it evolved, from article to article, and draft to draft, it absorbed the attention of sequential teams of invaluable research assistants: Mirna Adjami, Michele Beardsley, David Bosco, William Bradford, Dana Brakman, S. Chelvan, Sungjoon Cho, Cait Clarke, Aliya Haider, Sharon Kasok, Amir Licht, Neil McDonald, Anja Miller (now Manuel), Gordon Moodie, Paul Oostburg, Laura Palmer, Stephen Park, Heidi Parry, Akbar Rasulov, Donovan RinkerMorris, Khalil Sharif, Sven Spengemann, Andrew Tulumello, Eli Wald, Stepan Wood, Scott Worden, and Patricia Yeh. Several members of this group have become scholars in their own right, writing and publishing papers that I cite, including Lore Unt and David Zaring. Special thanks go to team leaders Tim Wu and later Annecoos Wiersema and Gabriella Blum, who worked with other students to organize the research necessary for specific chapters and who took charge of plugging holes in actual drafts.
