It has been a pleasure working with Valerie and Eileen on this book. I once got in trouble with librarians by predicting the end of the book because a book does not offer the capability for interaction.
But it is a beginning. I am hoping this will be a beginning of a dialog with you, the reader. A few of my friends and colleagues have contributed their perspectives in the following pages.
I would like to thank my wife, Karen, and my longtime secretary, Mary Coppernoll, for their help on this book, and all of my colleagues and friends for their support.
