In terms of computer literacy and competence, there are all levels of expertise in the population. In terms of computer comfort, however, there are only two groups: younger people, who find the technology easy to use and as simple as can be, and the rest of us, who were raised in the age of the magical knowledge system called books. As you might guess, I find myself in the latter group, and I am somewhat in awe of those in the former. I like tables of contents, chapter headings, the ability to read over what I just read by flipping back a page, the ease of finding a reference, and the warmth of holding a book on my lap or the comfort of having it in my briefcase or on my bedside table. We cannot, however, escape the fact that, as we approach the millennium, we are becoming more and more dependent on computerized information, the Internet, e-mail, and CD-ROM instructional systems. Enneking and his coworkers have produced a beautiful example of the latter.
