We would like to thank Kevin Hillstrom of ABC-CLIO for his invaluable guidance throughout this project. His flexibil- ity was much appreciated. Robin Tutt and Catherine Lafuente deserve thanks as the originators of the project. We also owe gratitude to Laurie Collier Hillstrom for her insightful con- tributions to Chapter 4, Profiles. Seattle University students Sydney Mead (Class of ’21) and Abigail Dean (Class of ’23) provided excellent and much appreciated research assistance. We hope you enjoy reading this book as much as we enjoyed writing and editing it. The importance of the issue cannot be overstated. Stacey M. Jones and Robert S.
