As a library user it's a pet peeve of mine. If I ever see a book in wrong place, I just put it back where it belongs. There's noting more infuriating than not finding a book and knowing it's somewhere in there.
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.
As a book user I really hate this misuse of syntax. This pet peeve of yours is not a library user.
