The "Report of Proceedings, Symposium on Information Theory" (London) first published this paper in Sept. 1950." The "Transactions of the IRE Professional Group on Information Theory" reprinted it in Volume: 1, Issue: 1, Feb. 1953, pages 102-104, Feb. 1953. We are not aware of offprints from either publication. Offered here is a reproduced typescript of the paper from Shannon's file predating the first publication. We have not compared it to the published papers. Shannon defines a typical communication system as consisting of five elements: 1) an information source. 2) an encoding or transmitting element. 3) a channel on which the signal is transmitted from transmitter to receiver. 4) a receiving and decoding device that recovers the original message from the received signal. And 5) the destination of the information. From the Abstract: ".The central problems to be considered are how one can measure the capacity of a channel for transmitting information; how this capacity depends on various parameters such as bandwidth, available transmitter power and type of noise; and what is the best encoding system for a given information source to utilize a channel most efficiently." PROVENANCE: The personal files of Claude E. Shannon (unmarked). the last of three examples in Shannon's files. REFERENCES: Sloane and Wyner, "Claude Elwood Shannon Collected Papers," #61.
