Librarian here. There is no pleasure of stumbling upon a book in the wrong place.
As a book user I really hate this misuse of syntax. This pet peeve of yours is not a library user.
A lot of university libraries clearly instruct users not to put books back after taking them off the shelf, because in putting it back "in the right place", they often get it wrong. Instead, one should put it in a designated place for the library staff to shelve it instead.
The Arcanum from it is a librarian's nightmare, I wondered what you thought of the description / if you've ever worked in a library that's too big to sort properly.
