Although many people find the Internet a handy tool for digging up all sorts of information, some still prefer to look things up the low-tech way -- in a book.
One reason might be that a book provides a tactile pleasure, as one hand firmly cradles the book's heft while the fingertips of the other hand gently scan the smooth surface of the pages, almost as if they are reading the text.
What's more, a "skyline" of reference books arranged on a shelf or desk top is an impressive sight, one that shows you are one ardent researcher.
Some recent reference works zero in on specific subjects and offer information that's unusual but useful -- and even some that modestly claim to be "perfectly useless."
