I saw something similar recently and couldn't find it, so I decided to make my own version of it that would make it easy for people to organize the Book Nook Boards to make it easier to find the one you're looking for. Each slot is lettered A-O (even though I've never had a nook go past N and there's no real slot for O) and it makes it's easy to find each board as you go through the instructions. Hope this helps... let me know!
