On MathSource I searched on ""NIntegrate" and found two interesting documents:

"The N Functions of Mathematica"

and

"Numerical Computation with Mathematica"

They explain quite a few things on NIntegrate (and other routines) that
isn't covered in the Mathematica book, such as, that NIntegrate in fact 
uses the mentioned Gauss Kronrod method.
