I WOULD LIKE TO THANK a number of people who helped me with the research for this book. They include David Oyer, Lucy Oyer, Sari Bourne, Scott Shackelton, and Renee Stowitzky. I also want to thank two anonymous reviewers for their comments, and most especially, Joanna Grossman for going over every page of the manuscript and saving me from the most egregious errors. As usual, too, I owe an enormous debt to the library staff of the Stanford Law School. I'd like to mention specifically Paul Lomio, Erika Wayne, Kate Wilko, and George Wilson. My assistant, Mary Tye, was a big help too; and of course, I have to thank my family for their everlasting support.
