The book by Shannon and Weaver (1949) is the classic; Shannon almost *is* information theory. There is more to it: The present lovely little book appeared first in 1965, but is still very relevant. I think it is a good next book to read. At least the mathematical part of the subject stays more constant over the years, as do the fundamental principles;-- that is what Ash's book is about. I especially liked ch 4 on error correcting codes, and the mathematical appendix which is centered around the Karhunen-Loeve theorem;-- the latter having found recent exciting applications in wavelet theory.
