"Friends of the Library Book Sale, Downtown Ithaca. May & October weekends - locals plan their schedules around attending the book sale. The first weekend of the three weekend stretch is the most expensive, but aside from rarities and first editions, nothing is over $4. Go on the first day and you'll wait in the longest lines, but you'll also get a glimpse of the folks who camped overnight to be first inside. Ithaca is a town full of advanced degrees, so it makes sense that book sale patrons often behave like band groupies when confronted with such a literary mecca. Everything, and I mean EVERYTHING, can be found at the book sale. 1970's craft magazines? Oh yeah. Science textbooks, history, biographies, loads of scifi, mystery and trade paperbacks? Yup. A huge children's corner, board games, movies on VHS and DVD, comic books, record albums... you get the picture. If you're in town when the sale is on, just go. You won't be disappointed."
