This link gives a list of references used for the course "Introduction to Systems Science" at SUNY Binghamton.
Here is a sample of books recommended by members of the cybernetics society as useful introduction to the science of Cybernetics. Quite a comprehensive list of books are mentioned.
This is quite an old article introducing cybernetics and information theory. See also here.
A recent article (compared with the two mentioned above) would be found here. Also, a very good exposition can be found here.
