Express Book Group in a Bag titles were created for situations when a book group may need a book title immediately, without first making a reservation. Express Book Group in a Bag titles can be checked out from the Reference Desk at the library on a walk-in basis. Reservations are not required for these titles, and an available Express Book Group in a Bag title can be checked out promptly on a valid library card. Like our traditional Book Group in a Bag service, these titles check out for 6 weeks and must be returned to the Reference Desk.
