The Friends of the Mercer Public Library will once again be holding its traditional Holiday Cookie Exchange. The fun starts at noon at the Mercer Public Library on West Margaret Street next Saturday, the 14th. Attendees are asked to bring three dozen homemade cookies, candies or other holiday to share and exchange in order to have a treat tray to take home. Besides the cookie exchange, those in attendance will have a chance to win some exciting door prizes. For more information, contact the Mercer Public Library.
