The porter spends his days in the Library keeping strict vigil over this catacomb of books, passing along between the shelves and yet never paying heed to the almost audible susurrus of desire- the desire every book has to be taken down and read, to live, to come into being in somebody's mind. He even hands the volumes over the counter, seeks them out in their proper places or returns them there without once realising that a Book is a Person and not a Thing.
