If you’re in need of some reading material on a weekend and are in the vicinity of Baltimore, Maryland, stop by The Book Thing and see what they’ve got. You can take it with you for free. Yup, no charge. The catch? The book is stamped “Not For Resale”, so if you are intending to profit from this venture, you won’t look too good. But otherwise, feel free to browse and pick what you like. As the FAQ says: Q. Is there a limit to how many books I can take? A. You can only take 150,000 per day per person.
