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.
Some libraries supposedly collect statistics on books used in the building, measured by counting books in the to-be-reshelved area, for use when lobbying for funding.
