Parcel post, the delivery of packages through the mail, began in the United States on January 1, 1913. Libraries had long lobbied for a special rate for library materials sent through the mail, and in 1914 the postmaster general authorized the shipment of books at the parcel post rate. This decision opened up significant possibilities for library service to geographically remote poputlations. One of the first librarians to realize the potential of parcel post and library service was Matthew S. Dudgeon, the Secretary of the Wisconsin Free Library Commission (WFLC). Under Dudgeon's leadership the WFLC began implementing a system in which any resident of the state could request a book from the major libraries in Madison including the University of Wisconsin Library and the State Historical Society Library. There was little red tape involved. All that was required was a letter requesting a book along with the postage. Under the new postal rates a book could be sent anywhere within a 150 of Madison for an average of six cents and for greater distances for eight cents. Implementation of this system was facilitate by the fact that the President of the University of Wisconsin and the Secretary of the Wisconsin Historical Society served on the Wisconsin Free Library Commission board. An article about Didgeon's parcel post system appeared in the December, 1915 issue of American Review of Reviews.
