Forgive me for being blunt.
What did you do with the dolls?
That is going to be where the major infusion of spirit manifestation is.
Also, trust no one to clean your items, they have your personal energy within them
since you used them and you should be the one to clean them, no one else.
I will agree on this:
Until ALL Activity IS GONE,
you were posting about a demonic entity a weeks weeks back,
Until this entity and Anything else, be it the dolls who haven't crossed over,etc.
You should NOT be using any tools that you don't know how to properly navigate.
Any type of using of these tools will just allow the energy to manifest and you stated you
wanted it to leave your house.
So my advice would be to get your books and tools back, but get rid of the dolls if you still have them
and do not do anything "magical" until the "malicious entity" is gone from your house.
Cleanse your tools yourself, outside under the moon (one time should do the trick)
until this "malicious activity" is gone from your house,
but do not do anything else.
I hope this helps, because I seriously wish the best for you and your family,
