摘要：The Cleveland Medical Library began the delivery of books to members about four years ago, during the first two years the Library paid a man with an automobile a flat rate of $22.50 per week, with the result that the deliveries averaged about eighty cents per book. In 1932 an arrangement was made with a package delivery firm to make the deliveries at a rate of twenty cents per delivery, and the same amount for the return, although if a delivery were made at the same time to a member no charge was made for the return.
