Sometimes I'll be in a large used bookstore, like the kind of cavernous ones you find in places with cheap real estate, or at a charity sale and there will be a book with a title like "Learning J2SE 1.4" or "XHTML for Dummies" that is just utterly and completely useless.

I wonder if these books will eventually be interesting, the way old ham radio or slide rule manuals can be, or if they're just forever doomed to irrelevance.
