I was having a conversation with someone else before and they posed an interesting question.

In the library you can only find books that relate to you or your profession. However if you took one out would you be able to let another person read it. Even if they wouldn't be able to find the book in the first place.

If you were to take out a book from the library we could then see if I was able to see it.

[Slows down slightly as he'd been talking rather quickly]

I'm sure it wouldn't matter in the grand sheme of things. But it would be an interesting way to test how powerful the place is.
