I don't see the point of this thread. You said it yourself that you took most of these books from another thread. Instead of listing a bunch of "great" books, pick one up and actually read it.
A lot of people seem to think that they have to get all the "right" books. They spend so much time finding these "right" books for a collection they think is really admirable. The fact of the matter is, for a person who really cares about learning math, there is no difference between Apostol and Spivak, or Stewart and Spivak. There are plenty of resources out there for people who want to learn calculus or another subject. There is a time for finding those resources when you hit a roadblock, but first of you should pick up ONE book and start doing math.
