We've got you covered! We actually have a system for recording browsing statistics (i.e., tracking how many times a book has been used, even if it hasn't been checked out), as well as a specific system for shelving that the library staff are trained in. While we appreciate your diligence, it's actually better for the library if you return books you've taken off the shelves to the front desk. Rather than trying to reshelve the books yourself, the library staff will be more than happy to do it for you!
