I've been reading about Claude Shannon and information theory quite a bit lately so I thought I'd share some of things I've seen, both on the free Web and in journals & conferences:

• The best place to start is Robert G. Gallager's "Claude E. Shannon: A retrospective on his life, work and impact" from the IEEE transactions on information theory. 47(7): 2681-2695.
  
• From the 1994 IEEE Security Technology conference, "Claude Shannon's cryptography research during World War II and the mathematical theory of communication," by Everett M. Rogers.
  
• From the AIP's 21st International Workshop on Bayesian Inference and Maximum Entropy in Science and Engineering, "The information revolution in yet to come (A homage to Claude E. Shannon)," by Alberto Solana-Ortega. This is a kind of expansion and rethinking of Shannon's ideas and is therefore quite interesting.
  
• Another good Shannon bio, taken from his collected works. This one's by N.J.A. Sloane and A.D. Wyner, the editors of that book.
  
• Speaking of the collected works, here it is. If your math/engineering/computer science collection doesn't have this book, it should. I know we didn't so I just ordered it myself.
