$30 Thursdays: Literary edition

What shall we explore on this week's edition of $30 Thursdays.  How about books?  And, yes, I know you guys read at least one of these in high school (I'm looking at you, Gatsby), but they're still great.  And can you name anything else you can buy for less than 30 bucks that took this much effort to create?
