Any good books on data structures

I am trying to brush up on my data structures and algorithms knowledge. Thusfar I was working on the algorithms part where the algorithm design manual helped me a lot. Unfortunately, that book hardly discusses data structures... Can anyone recommend a book on data structures that is "on par" with Skiena's book?

Try Data Structures & Algorithms in Java by Robert Lafore. It's a few years old but the basics are still valid.

Don't know about data structures, but the definitive work on algorithms is The Art of Computer Programming Volumes 1-3.

#3: Now The Art of Computer Programming, Volumes 1-4A Boxed Set

I have used & liked introduction to algorithms by Cormen & others. I also like Functional Data structures by Chris Okasaki. There is always Structure and Interpretation of computer programs. But there is still a lot of stuff not captured in books. What I would really like is an online resource with a taxonomy of data structures with links to various algorithms, sample applications, implementations in various languages and so forth. Sort of like what mathworld.wolfram.com has done for mathematics.

Wikipedia's list of data structures page is a start.
