September is Library Card Sign-Up Month and the Incredibles are celebrating the power of libraries! Whether you already have a York County Public Library Card or still need to sign up, all ages are invited to visit their library this month. Special programs will help you explore the library's many resources. Take part in our scavenger hunt to find all the incredible things your library has to offer, too. Then tell us what incredible things you like most about your library and be entered to win a prize. Now is the perfect time to visit your Library and check out something incredible.
