You target any or all objects within 10FT of you that contains written information (this can include images and diagrams).  The spell replicates this information keeping it within the pages of the book used within the casting of this spell.  
As an action the caster or creatures you designate can read the contained knowledge.  Any other creature that tries to read the book is met with blank pages.

Casting the spell again installs any new information and you can choose to discard any information captured from previous castings.
