Panamerican Health Organization) and in Japanese (published by Maruzen). Why have I been so lucky? I think it is because I selected some amazingly talented people to read and criticize the various editions of this book. As I look over the names of the various people who read one or more of the manuscripts for the preceding editions, I am yet again awed by the lustre of their reputations. And I am yet again aware, almost painfully so, of how much of their wisdom has gone into "my" book. Once again, I say thanks to them. Here are their names:
Robert E. Bjork
Kirsten Fischer Lindahl
Estella Bradley
Karen Kietzman
L. Leon Campbell
R.G.E. Murray
Morna Conway
Evelyn S. Myers
Cheryl A. Cross

Betty J. Day
Michael Pohuski
Robin A. Day
Gisella Pollock
Barbara Frech

And now I give thanks, very sincere thanks, to those colleagues who read all or parts of the manuscript for this Fifth Edition: Robert J. Bonk, L. Leon Campbell, Betty J. Day, Robin A. Day, Richard H. Duggan, Ronald J. Hirschhorn, Linda M. Illig, Robin W. Morgan, Nancy Sakaduski, Brian H. Schaffer, and David W. Smith. In addition, I want to single out two individuals who contributed substantially to initiating and organizing much of the new "electronic" information that went into this edition: Bernice Glenn, a very knowledgeable consultant, and John Wagner, the very knowledgealble Senior Editor at Oryx Press. I am in debt to all of these good people.
