Nice! I love books and I love math.
I own the usual suspects: Stewart, Dummit, Hatcher, Axler, Munkres, and Baby Rudin.
Books are so expensive so I usually buy the ones that are widely recommended. Also, it has taken me a while to learn *how* to "read" a mathbook (David Bessis' great book helped). I recently started with Hatcher.
Do you have a favorite mathbook?
