A quantitative information theory is developed for both classical and quantum spin systems. The theory is examined by heavy numerical simulations, which show that the information embedded in each weight of the system increases with the size of the system. The difference between the notions of capacity and information is examined carefully and gives an explanation to the surprising result that the capacity per bit can be greater than one.
