Suggestion:
So, first off, cool mod. (I personally would have did some things differently, but I am not the creator)
Second off, I think this mod has bigger potential then what it currently is using.
You got the wizard/mage part down, and I think it would be cool if the mod expanded to other 'classes' like warriors who specialize in swords and shields, with damage or defence magic/abilities. They would be able to fuse books, just like the current wands, into shields and swords.

There could also be ninjas, who specialize in speed, status effects, and the ability to confuse the target, hide, or run away. They would use throwing weapons, knives, and daggers, and they could fuse books into their knives/daggers.
I think you get the idea, and it could include archers, warriors, ninjas, berserkers, and others possibly.

My second suggestion is, the baubles system is extremely limited in my opinion. I think that there should be a no-effect item for each bauble slot, and you can find books or something and then choose what kind of accessory you want to enchant with the effect. As of now, there are like twenty rings, maybe nine charms, and fifteen pendants? This is very limiting as you can only equip two rings, (I guess minecraft people only have two fingers that are ultra short?) and most of the effects are in the rings.
My idea would allow you to customize your effects a little bit more is all.
