Introductory book on Topology 

I have been charged with ordering some topology books for our library.  The books must be intended for undergraduates.  I have thought of:
Topology: by Munkres
Topology from a Differentiable Viewpoint: by Milnor
Algebraic Topology: by Hatcher
A Combinatorial Introduction to Topology: by Henle
Homology Theory: by Vick
Topology: by Hocking and Young
From Calculus to Cohomology: by Madsen and Tornehave
Are there some good books that I am missing?
 A: I might also recommend checking out the following (reviews are generally well accepted and they are Dover (except the last) books, so the price is excellent):
Introduction to Topology: Third Edition (Dover Books on Mathematics) Bert Mendelson (Author), Mathematics (Author)
Counterexamples in Topology (Dover Books on Mathematics) Lynn Arthur Steen (Author), J. Arthur Seebach Jr. (Author)
Introduction to Topology: Second Edition (Dover Books on Mathematics) Theodore W. Gamelin (Author), Robert Everist Greene (Author), Mathematics (Author)
General Topology (Dover Books on Mathematics) Stephen Willard (Author)
Topology (Dover Books on Mathematics) John G. Hocking (Author), Gail S. Young (Author), Mathematics (Author)
Topology (Undergraduate Texts in Mathematics) K. Jänich (Author), S. Levy (Translator)
I should have also noted that many undergraduate students find the transition to these subjects difficult and they want to see and do problems. It doesn't hurt to make these two also available because cost is very reasonable.
Schaums Outline of General Topology (Schaum's Outline Series) Seymour Lipschutz (Author)
Topology Problem Solver (Problem Solvers Solution Guides) The Editors of REA (Author)
Lastly, if you have a another college near you, you might also peruse their collection.
A: This has been treated here many times before.  Please see the five articles linked from the "Topology: Book recommendations" section of List of Generalizations of Common Questions.
A: Elementary Topology: Problem Textbook is a not so famous excellent book of Topology.
A: Differential forms in Algebraic Topology, by Bott & Tu: though it overlaps a bit with the one of Madsen & Tornehave, an excellent book.
