Cover all that dust collecting on your bookshelves with some knowledge, a few good yarns, or some good CDs, at least, from Half Price Books -- a chain of stores well-stocked with new and used books, and other media. If you're in a pinch, go for their "Books by the Yard" deal -- that's less than 20 bucks for three linear feet
of mixed reference books, law books, and those faux-antique Reader's Digest Condensed Books. Sell your books here too; you won't get much, but they'll kick back cash or store credit, along with a discount on your next purchase. And the staff -- well, they've read enough to make you feel how much you haven't. When you're done being mad, you'll find them very helpful.
