title: A good intro to information theory, please?
body: <p>I know about <a href="http://en.wikipedia.org/wiki/Information_entropy" rel="nofollow noreferrer">Wikipedia</a> and MacKay's <a href="http://www.inference.phy.cam.ac.uk/itprnn/book.html" rel="nofollow noreferrer">Information Theory, Inference, and Learning Algorithms</a> (is it appropriate as textbook?). A textbook starting with Shannon's entropy and going through Conditional entropy and Mutual information is sought... Any idea? If you  are following such a course at your university, which textbook is used?</p>
  
  <p>Thanks.</p>
