^ From the third paragraph of the story: "Each book contains 410 pages; each folio, 40 lines; each line, virtually fourscore blackness letters." That makes 410 10 xl x fourscore = 1,312,000 characters. The fifth paragraph tells us that "at that place are 25 orthographic symbols" including spaces and punctuation. The magnitude of the resulting number is found by taking logarithms. However, this adding only gives a lower jump on the number of books as it does not accept into business relationship variations in the titles – the narrator does not specify a limit on the number of characters on the spine.
