MetaCrawler would not exist were it not for the help of a great many people. Greg Lauckhart has been invaluable in its recent development, in particular the development of the Java interface and numerous internal architecture improvements. Nancy Johnson Burr, Voradesh Yenbut, Rick White, Art Dong, Steve Corbato, Tom Profit, Terry Gray, and Erik Lundberg have been instrumental in keeping the MetaCrawler service up and running. Thanks also to Ed Lazowska for his insight and support. Finally, thanks to Mary Kaye Rodgers for her patience with long nights and impending deadlines.
