4 During mytenure at Novell from 1989 to 1994, I worked with and around its excellent education andcertification department. At Novell, I witnessed the growth and development of the firstreally big, successful IT Certification program one that was to shape the industry foreverafterward. This experience helped push my writing and teaching activities heavily in the cer-tification direction. Since then, I ve worked on nearly 100 Certification related books, and Iwrite about Certification topics for numerous Web sites and for 1996, while studying for various MCP exams, I became frustrated with the huge,unwieldy study guides that were the only preparation tools available. As an experienced ITprofessional and former instructor, I wanted nothing but the facts necessary to prepare forthe exams. From this impetus, Exam Cram emerged: short, focused books that explain examtopics, detail exam skills and activities, and get IT professionals ready to take and pass 1997 when Exam Cram debuted, it quickly became the best-selling computer book seriessince.
