LE Books

Hi

I am an SD consultant and i have been looking for some reading material (Full Books) on some of the sub modules of LE Like Shipping, Transpotation and WM. I have checked the net but i could not be sure about the books that i came across as i would want the book to take me through like an implementation guide does. Can you please suggest me some books which i can refer to from an implementation point of view?

Thanks.
