The C++ standard library extensions : a tutorial and reference / Pete Becker. hardcover.
Here is a book every C++ programmer needs. The TR1 library, which extends the C++ standard library, has most of its ideas from the Boost library, and is powerful. A line of code deserves a page of discussion. As such, it tricky to use or use well.
This book, by a core leader of C++ standards groups,
is mostly a reference volume. Nowadays you usually use the web for reference, but this book will save you a lot of searching.
C++ programming has advanced so much since I started with it 10 years ago. Not that the language changed much, it is more that we use it differently with templates and the standard library. I wish I had time to read this book page by page.
