The seminal introductory work for me was the Undergraduate text "Coding and Information Theory", by the late Richard W. Hamming, 1980, ISBN 0-13-139139-9 (perhaps one of the 1st books to have an ISBN number).  It cost me $26.35 (CDN), hardcover, and I devoured every morsel of it. His later work "The Art of Probability" is also worth a read for anyone who still believes in randomness. outer --  Random : An infinitesimal, yet omnidimensional, god of science. Random often appears in the guise of a trickster named Error.
