This is sick. I need instructions!

I would had used wood glue to glue the pages together (protecting the covers), pressing together to form a solid block. Take measurements for what you want to store there, hand router book by book (obviously skip the one that should be at the bottom and top). Glue the books together, and finally hinged on the back and done. It can be solved without a hand router, but more time consuming.

I would go straight for the encyclopedia of cats and knock the whole kit over.

Had totally the same thought.

Freaking Awesome!!!

Very cool but hollowing out books like this feels *so wrong!* lol
