Open sources is a book that came out of O'Reilly publishing in February of 99. It features essays from a number of top minds in the open source revolution. A fortune file of quotes is available (along with other info) at http://www.dibona.com. It includes essays from Linus, Raymond, Larry Wall, Jerry Springer (just kidding), Michael Tieman, and others.

The Open Sources book is available online for free (as in "free beer") at:
