If you're pacing the floors at your place and you're restless and bored out of your mind, you may have Cabin Fever.
Or not - I'm no doctor.
What I am is a dude who's been to his fair share of used book stores, and as far as they go, Cabin Fever Books is a good one. The barely used books that line their shelves are meticulously categorized and organized, which makes finding what you're looking for a breeze. When you find what you're after, chances are you'll find the price to be a little more than what you're accustomed for paying for a used book. But, from what I saw, the books available were in near pristine condition, so the slightly higher prices are justified.
I recommend Cabin Fever to all you avid book collectors out there for a good store to build your personal library with quality used books.
