Re: Algebraic Topology by A.Hatcher.

If you're looking for a good book on algebraic topology, I'm currently reading "Algebraic Topology" by Edwin H. Spanier, and I love it. It's rock hard, but rewarding. Possibly not a good introduction to the subject (I've seen a bit of algebraic topology before, but only in books for physicists which omit technical details), but if there is a copy in your library you should check it out at least.
