From the room in your house devoted to clutter to the dust bunny shaped like Elvis hidden in your dresser drawer, Americans hang on to a lot of crap. Former journalist LISA TRACY sheds light through her personal experiences by exploring things we hold onto, not because of materialism, but as a way to connect to our family history. Tracy visits Decatur Library for a reading and signing of her new book, Objects of Our Affection: Uncovering My Family's Past, One Chair, Pistol, and Pickle Fork at a Time. Free. 7:15 p.m. 215 Sycamore St., Decatur. 404-370-8450. www.georgiacenterforthebook.org.
