Here are some more very old and out-of-date books:

• The Art of Computer Programming, vol. 1-3 by D. Knuth. These were published between 1968 and 1981! We are not using vacuum tubes anymore, people! Everything in these books are lame. Where is the discussion on Python and Ruby?

• Computers and Intractability: A Guide to the Theory of NP-Completeness by M. R. Garey and D. S. Johnson, 1979. Super lame! All these problems have been solved by now, probably.

If a book wasn't written in the last three years with focus on Python, then it's not worth reading.
