Acknowledgments

We continue to be extremely grateful to our colleagues at Boalt Hall of the University of California, Berkeley, and at the University of Illinois College of Law for the superb scholarly environments in which we work. Our colleagues have been extremely generous with their time in helping us to understand the law better. And in one of the great, ongoing miracles of the academic enterprise, we continue to learn much from the students whom we have the pleasure to teach at Berkeley, Illinois, and elsewhere.

We should also thank the many colleagues and students at other universities who have used our book in their classes and sent us many helpful suggestions about how to improve the book. We particularly thank Joe Kennedy of Georgetown, who has given us remarkably thorough and singularly helpful comments on improvements in the text.

We’d like to thank the following reviewers for their thoughtful commentary on the fifth edition: Howard Bodenhorn, J. Lon Carlson, Joseph M. Jadlow, and Mark E. McBride.

We would also like to thank those who have provided research assistance for this sixth edition: Theodore Ulen, Timothy Ulen, and Brian Doxey. And, also, for their long-time support and help: Jan Crouter, Dhammika Dharmapala, Lee Ann Fennell, Nuno Garoupa, John Lopatka, Richard McAdams, Andy Morriss, Tom Nonnenmacher, Noel Netusil, Dan Vander Ploeg, and David Wishart.

Finally, we owe particular thanks to our assistants, Ida Ng at Boalt Hall and Sally Cook at the University of Illinois College of Law. They do many big things to help us get our work done, as well as many little things without which much of our work would be impossible to do. Thanks so much.
