This book is dedicated to Peter for giving me the time and space to embark on this project; to my parents and sister for their encouragement and support; to my colleagues and students at Penn and beyond, who have challenged me to be the best librarian and teacher that I can be; and to Teddy, who helps me keep everything in perspective.

This book is gratefully dedicated to my wife Eileen for her love and patience, my daughters Sandra and Nancy for making parenting both memorable and enjoyable, my mother for instilling a love of reading, and my father for encouraging curiosity. I am also very appreciative of all the interesting questions posed by Caltech's faculty and students that were instrumental in my growth as a reference librarian.
