The best book I've found for the C++11 Standard Library is
The C++ Standard Library - A Tutorial and Reference, 2nd Edition
by Nicolai M. Josuttis. (The first edition covers the library prior to C++11.) Mr. Josuttis has also written Object-Oriented Programming in C++
and co-authored C++ Templates: The Complete Guide
with David Vandevoorde.
Note that some features of the C++11 Standard Library have not yet been implemented in gcc :-( and must be obtained from one or another of the c libraries.
I like Mr. Josuttis' Object-Oriented Programming in C++
because, in contrast with many other C++ books I have tried to learn from, it is a treatise on pure C++, not a book about C with use of the << and >> methods and a few chapters in the back about classes and methods.
