Having served faithfully as book review editor for a year and a half, Dr. Stone has become a full-fledged member of the Editorial Board of the Archives of Internal Medicine. This brings the number of associate editors up to eight. We take pleasure in welcoming him to a job whose main reward is the opportunity for hard work, gratefully acknowledged but little known to the casual reader. What special attributes have been responsible for Dan Stone's rapid progress as book review editor and critic who manages a multitude of jobs with skill and efficiency? Not only is he competent, but he achieves his editorial objectives with that appreciation of form which characterizes style. He has a keen eye for detail and a quick wit. Whether it be expounding clinical puzzles to undergraduate students or writing a keen commentary on a manuscript, he uses his insight with care but with dispatch.
