Make sure the books are in the right place otherwise you'll probably have to reload and try again i'm afraid, from the wiki page -

The pedestal with the fangs - Gnashing Blades

The pedestal with the pincers - Delving Pincers

The pedestal with the tentacles - Boneless Limbs

The pedestal with the eye - Prying Orbs
