Looking for something charming (and free) to entertain holiday company? Take them to Special Collections in the Allen Library (downstairs) where about 150 pieces of pop-up and moveable children’s books, some dating to the 17th century, are now on display as part of a new exhibit called Merry Company: Pop-ups, Movables & Toy Books. Suzzallo also has a smaller display of vintage books, located by the stairs leading to the Allen Library. The exhibit runs through March 16, 2012.
