Rick lelovsek is one of the "old timers" in computer medicine, developing and using computer systems for over 15 years. At Duke University, he developed one of the first computerized medical records for obstetrics and gynecology and collaborated with Drs. Stead and Hammond in the development of billing and accounting systems. A founding member and current officer of the American Association for Medical Systems and Informatics (AAMSI), he heads up and writes a quarterly newsletter for a special interest group in computers for the American College of Obstetricians and Gynecologists. He is a genuine (medical) "computernik." . I was asked as a favor to review his manuscript and suggest any needed changes before it was sent to a publisher. (He was not at that time planning to send it to Springer-Verlag.) Reading it was one of those pleasures I usually associate with a review article that finally explains those things about a subject that I was aware of but never really understood. I was familiar with practice billing, for example, but didn't really know the whys and hows of it all. Doctor's Office Com­ puter Prep Kit has filled the gaps in my knowledge with superb detail.
