Algebraic Topology: Home Page

Notes, books, etc.

There is quite a lot of useful material on the webpage of Allen Hatcher, at Cornell, as well as other places.

A good, leisurely set of notes on the basics of topological spaces by Hatcher.
An excellent book, "Algebraic Topology" by Hatcher. This is available as a physical book, published by Cambridge University Press, but is also available (legally!) for download for noncommercial personal use from the link given. Chapters 0,1,2 will be especially useful for this unit.
Elementary Topology. Textbook in Problems by Viro, Ivanov, Kharlamov, Netsvetaev. Material on topological spaces and algebraic topology with lots of nice exercises.

And a couple of other recommended books (not online):

W.A.Sutherland, Introduction to metric and topological spaces, Clarendon Press, Oxford. (For basic material on topological spaces.)
Munkres, Topology, Pearson Education.
