We would never have been able to complete this book without the contributions and kindnesses of many people. We particularly thank Barry Kellman for sharing with us issues, ideas, suggestions, and his passion for getting people to see the problem of biosecurity in new ways. We also owe a debt of gratitude to Ben Berkman for reading drafts of the manuscript and always providing helpful feedback. J. J. Welling provided us with timely and accurate help in researching specific issues covered in this book. The editors at Stanford University Press have been patient with us, and we appreciate their willingness to allow us the time we needed to finish this book. Finally, we thank our families for enduring yet another project that has often occupied our time and attention.
