In learning this process I have found that many of the older sources 
were very helpful. The books I've found (in English) are listed below. 
There are many contradictions, so the most reliable information comes 
from the techonogists (Cartwright and Industry journals) Jon 
Goodman confirmed much of this. There are some errors in Kolb which made 
things very difficult for us when were trying to learn on our own. Hope 
this is of some help.
