To make some quick books for some of your scenes, I use either gift wrapping paper or fluorescent posterboard, tape, a large black marker, and a puzzle box (you can have pieces in it, after your haunt just unwrap it).
Wrap the puzzle box with the warapping paper or posterboard, tape the edges then with a marker write on the side that will stick out on the shelf and the front cover what title you want and your done.
Here are some different titles I have used in my scenes....
Spells, Potions, Brews, Body Parts, Toad Recipes, Ogar Parts, 101 ways to cook rats.
