I can afford "free"

Click that link above and you're taken to a world of books whose copyrights have expired...and that are available for download FOC. There are over 20,000 titles in the Gutenberg Project's list. I'm not sure which to recommend, but given the price tag (free) and the subject matter (literature), I thought Adam Smith's "An Inquiry into the Nature and Causes of the Wealth of Nations" was an appropriate choice. Enjoy the read!
