what do you want to know about topology? there are general books on things like metric spaces, and general topological spaces.
then there are books that try to introduce the detaield study of specific geometric objects from a topological standpoint, like classifying 2 manifolds, as spheres with handles.
then there are introductinos to fundamental concepts like covering maps, and their relation with the homotopy clases of loops in the space, i.e. which study spaces essentially up to deformation.then there are global studies of manifolds of higher dimensons, and the tools that requires like homomology and cohomology. It is common to introduce differentil calculus here and study smooth manifolds, and de rham cohomology, and chern cohomology classes, to study obstruction to embeding manifolds in euclidean and projective spaces in small codimension.
then there is knot theory, and I guess I am running out of thigns i know about. Oh yes, the general theory of bundles.
I recommend Milnor's Topology from the differentiabkle viewpoint, and Bott- Tu's Differential Forms in algebraic topology, for a beautiful blend of algebraic and differential tools in topology, used to prove deep theorems.
Guillemin pollack lso have an expanded version of MILNORS BOOK, WHICH IS BEAUTIFULLY DECEPTIVE IN ITS IMPRESSION THAT THe STUFF IT IS DOING IS EASY.
Milnor is much better and more substantive, (and shorter and cheaper)but their book reads easier.
andrew wallace always wrotes with the student in mind and is always readable.for trivial point set topology, and formlaism I myself started out on kelley's general topology, but that is boring and sort of vacuous.
