The authors are grateful to the many, many people who have helped us develop the theory and practice of mapping. There are simply too many to name! We would be remiss, however, if we did not offer particular thanks to Jocelyn Hale and all of the staff members of The Loft Literary Center for letting us use their story in a fictionalized form that works best for instructional and confidentiality purposes.

We are also quite grateful for the strong encouragement Alison Hankey, our editor at Jossey-Bass, has given to the book all along, and for the additional help of the marvelous Jossey-Bass team, including Rob Brandt, Nina Kreiden, David Horne, and Diane Turso. Finally, we would like to thank the three anonymous reviewers of an earlier version of the book manuscript.
