Independent Bookstore Day is a one-day national celebration that takes place at indie bookstores across the country on the last Saturday in April. Every store is unique and independent, and every celebration is different. But in addition to authors, live music, cupcakes, scavenger hunts, kids events, art tables, readings, barbecues, contests, and other fun stuff, there are exclusive books and literary items that you can only get on that day. — IndieBound.org
