THE STACKER is one of several library functionaries permitted access to the interior of the library building. After THE SEARCHER locates and removes a book, it is THE STACKERís job to collect that book, route it and eventually replace it on the shelves. As such, he shadows THE SEARCHER and can be seen continuously shelving and reshelving on the 3rd and 4th floor. He is enamored with THE SEARCHER.
