Best book to learn the C++ STL?

[Ch1156]

I am reading a few books to improve my C++ and one of them mentions the STL and how its so big that entire books have been written on it, i'd like to learn that as well, what is a good book to get for learning that? Also is there any books or websites on learning the member functions of c++? by member functions i mean like

vector<string> vect;

vect.pop_back();
