This September we are doing something new for Library Card Sign-Up Month! Your Algonquin library card will act as a coupon card at select Algonquin businesses from September 1st to 30th. A complete list of business and their respective deals can be found here. The design on the card does not matter, as long as it is a card from the Algonquin Area Public Library District. Don’t have a library card? September is the perfect time to sign-up for yours!
