I didn't cleanse mine because they had just reshly stocked it. So, the odds of it being exposed to negativity were slim to none, and I doubt that the machine would have crammed the notebook with negative energies by it's anger.
With her Journal - I forgot what she wanted for her Birthday and I REALLY needed to know because the night before. And the little bugger grew teeth and bit me... BIT ME. Sorry to reiterate that part, but I wasn't expecting it and it STILL amazes me at the idea of an object Awakening itself because of sheer swelling emotions layed within it, and attacking an Astral prowler with no orders or enchantment whatsoever. But, it's possible since other objects are alive.
I'd like to say that the difference between an object with a Spirit and an object that has been Awakened is that the Awakened object is aware of it's Spirit, and is able to act with some form of logic and intelligence, unlikme the object that just has a Spirit and reacts to different mild stimuli and has an existance on the Astral.
Awakening your Book might be a good idea for you, but it won't help it hide unless the Spirit can make it's own Wards... Which I'm not sure of its ability to do so. It is what I'm about to investigate further.
Off Topic Question: Does the Internet have a Spirit?! O.o

And all the boards did shrink;
Water, water, everywhere,
Nor any drop to drink."
