Matthew:
The idea of a "killer app" in publishing is a myth, at least in general
terms. (Consider that a book can be a "best-seller" with only 10's of K of
copies, out of 100's of millions of readers.) Because CDROM is a
publishing medium, you have to think in terms of what information is most
valuable to you. There are, in fact, many "killer" CDROM products that
deal with specific fields. What is your interest? Maybe I can suggest a
title or two that would get your blood running!
