Mumit's STL Newbie Guide
http://www.xraylith.wisc.edu/~khan/software/stl/STL.newbie.html
You can find a beginner's guide to the Standard Template Library (STL) language. This is not a highly graphical site, but then again it doesn't need to be. It shows how to write container objects, how to store derived objects in an STL container, and more.
