Greg Harvey has authored tons of computer books, the most recent being Excel Timesaving Techniques For Dummies and Roxio Easy Media Creator For Dummies, and the most popular being Excel 2003 For Dummies and Excel 2003 All-In-One Desk Reference For Dummies. He started out training business users on how to use IBM personal computers and their attendant computer software in the rough and tumble days of DOS, WordStar, and Lotus 1-2-3 in the mid-80s of the last century. After working for a number of independent training firms, he went on to teach semester-long courses in spreadsheet and database management software at Golden Gate University in San Francisco.His love of teaching has translated into an equal love of writing. For Dummies books are, of course, his all-time favorites to write because they enable him to write to his favorite audience, the beginner. They also enable him to use humor (a key element to success in the training room) and, most delightful of all, to express an opinion or two about the subject matter at hand.Greg received his doctorate degree in Humanities in Philosophy and Religion with a concentration in Asian Studies and Comparative Religion last May. Everyone is glad that Greg was finally able to get out of school before he retired.
