Across Spang Street overlooking the duck pond stands the Blank Book Company, an ancillary business founded by Bare in 1887 to produce ledgers, tablets and composition books from the mill's paper stock. Practically all of the book factory complex survives, including the impressive three-story Office and Warehouse Building (1900) constructed in a castellated fashion with quarry-faced ashlar cut from local "blue" limestone. The oldest building in the five-building complex is the two-story brick Binding Building (1888). The others include the Printing House (1895), a three-story brick building; the brick Shipping and Stock Room Building (1905) at three-stories; and the five-story brick Warehouse built in 1914. An original fire station is located in the yard in front of the stone Blank Book building.
