Benny - that occured to me also. I'm thinking, pick new books on the subject each visit until you run out of books, then go back are re-PR the ones that stuck out from the rest. Let your intuition guide you.
I've had so many (new) things on my mind these past several weeks that I forgot to do this, and I had been meaning to for a long time - I'll start this week at the library for sure. Now that I'm really "into" the PR methods I want to see what this added measure does to my studies.
