Library

I'm stuck in the library. I can't find out what to do with the crystal. I have no idea how to charge it, can't get in the drawers, and I have one book that I can't find a place for.

First problem: whats the name of the book you can place ?

if you have one book left and the crystal put the book on the floor where the drawings are then click on the book to open it place the crystal in the book then use your crystal on the crystal ball
