You can never have enough books around the house. Especially used books. Disregard the unread stack on the nightstand; it's time to re-up once again at the 20th annual Cambridge Friends School Book Sale. Tonight the sale opens with a special event featuring readings from two writers who also happen to have children at the school: bestselling author of "Will in the World" Stephen Greenblatt and Caroline Elkins, who won the 2006 Pulitzer Prize for her book "Imperial Reckoning." 6 p.m. Cambridge Friends School, 5 Cadbury Road, Cambridge. 617-354-3880. cambridge friendsschool.org
