For all you "book-readers" out there, the Morgan Library currently has an exhibit on Ernest Hemingway entitled "Ernest Hemingway: Between Two Wars". It includes early scripts, short stories, and heavily edited manuscripts for his major novels, as well as photographs, an oil painting of him, and other personal items.
Admission to the museum is $12 (but if you go Friday between 7pm and 9pm you can get in for free!), and it's located at 225 Madison Ave at 36th. The exhibit ends January 31st, so get to it before there's nothing left to get to!
