The Medford library Friends book (and bake) sale, May 16-17. Im on the book sale crew and I can tell you, the selection is definitely worth checking out. And the bake sale always has some really good homemade stuff.
Note that the Friday evening event is for Friends members only, but membership is cheap and you can join on the spot.
