The Wall Street Journal had an article today (I'd link to it, but you need a paid subscription) about online swap markets for books. While the sites listed in the article differ slightly, they are all an attempt to cut out the middleman in the sale and purchase of used books (and in some cases DVDs, video games and audio books). In general, the idea is that registered users post their material and a point value is assigned based on the market value of the item posted. This becomes the users currency to trade items with others. Each site differs in terms of fees charged by the site owner and for shipping. Hmm . . .
