[fluctor]

I have a stack of statistics books that I will flip through if I need explanation or illustration of a new concept. Usually one will help me out better than the others, but the combination of the different explanations usually improves my understanding.

I suppose this is really a parallelization of the "third textbook" model (i.e., if the third textbook you try when learning something new seems "much better" than the first two, it might because you actually did learn some things from the first two).
