The Robert Wood Johnson Foundation Anthology series is very much a team effort. We are fortunate to be working with such a talented group of people, most of whom have been together through all five volumes of the Anthology. We appreciate not only their high level of professionalism but also the degree of personal warmth that has made working together such a pleasure.

We would first like to acknowledge the singular contribution of Frank Karel. His vision helped launch the Anthology series, and he continues to offer his guidance, wisdom, insight and good humor. Since the first volume, each manuscript has been scrutinized by a panel of outside reviewers: William Morrill, Patricia Patrizi, and Jonathan Showstack. They make an invaluable contribution to every chapter and to the book as a whole.

The chapters are edited by C. P. Crow, an extraordinarily knowledgeable and gifted editor, and Molly McKaughan, who, as a writer and as co-director of the Foundation's Grant Reporting Unit, brings a unique perspective to the Anthology. Our thanks to both.

Within the Robert Wood Johnson Foundation, many people play an important role. We wish to thank Deborah Malloy for her tireless efforts in organizing materials—and people—at the Foundation; Sherry DeMarchi for her willingness to be of assistance throughout the entire process; Linda Potts for her high level of professionalism in handling administrative matters; Paul Moran for stepping in so ably after Linda's retirement; Joseph Wechselberger, Carol Owle and Carolyn Scholer for handling financial matters with such efficiency; Richard Toth and Julie Painter for assuring the accuracy of numbers pertaining to grant awards; Emily Snell for her research assistance; and Hinda Feige Greenberg for tracking down hard-to-find materials.

Many others have made a significant contribution. We would like to express our appreciation to Ty Baldwin, who enters editorial changes, and to Chris Chang, who is our fact checker. At Jossey-Bass, Andy Pasternack, the health series editor, and his colleagues Gigi Mark and Amy Scott handle production and distribution adroitly.

Various people reviewed the book, either in part or in whole. We thank Michael Beachler, Robert Campbell, Chris Conley, Ruby Hearn, Paul Jellinek, Nancy Kaufman, Terrance Keenan, Kate Kraft, Marion Ein Lewin, David Olds, Michael Rothman, Lewis Sandy, Steven Schroeder, Pauline Seitz, Warren Wood, and Judith Whang.

We would be remiss if we did not express our gratitude to each of the authors for the high quality of their work and for their patience in dealing with what must have seemed like endless queries from the editors.

At Health Policy Associates, we would like to thank Greta McKinney for handling the bookkeeping and financial reporting so efficiently, and Elizabeth Dawson for shepherding the book through its final stages.

Finally, we owe a special debt to John Rodgers. John has excelled as a researcher, editor, and manager of the entire process from beginning to end. This will be John's last year as research and editorial associate for the Anthology; now he moves on to devote himself fully to health research. He has made an invaluable contribution, and he will be missed.
