I found a nice way comparing school books with other things in life.
School books are like ladies, they are good by all means, but they are so covered up with bullshit and unessesary info that it's hard getting the core or essence of it. You try to read and understand it all, but that thing you'll need will be hard to find and easy to be overseen, due to all the other shit in it.
Therfor, buy whores! No chit-chat or unessary stuff, get what you want WHEN you want. As same goes for the books, go internet! Because the text you are looking for is inside the book yes, but it's covered with other stuff you don't need (in that situation) and it will be hard to find. Ask internet and internet gives you the answer right away!
There, I tried to be funny but failed
I guess the reason why you posted was to get hand on the knowlege about the subject the fast and easy way. I am sorry that I canot help you, because I have no clue what it actually is about, best thing would of course be to read the books and try to understand it - because it will stand there, but second thing would be to ask internet for advice.
You were a little unlucky this time, since everyone thought this was a nice situation to start a flamewar on, however - ignore this and continue your journey on google, I am sure you can find more help there and sollution for what you are asking for
