William Garrett had another visitor that day in the person of a contemporary and colleague from the library, one George Earle. Earle had been one of those who found Garrett lying insensible on the floor just inside the 'Class' or cubicle (opening upon the central alley of a spacious gallery) in which the Hebrew books were placed, and Earle had naturally been very anxious about his friend's condition. So as soon as library hours were over he appeared at the lodgings. 'Well,' he said (after other conversation), 'I've no notion what it was that put you wrong, but I've got the idea that there's something wrong in the atmosphere of the library. I know this, that just before we found you I was coming along the gallery with Davis, and I said to him, 'Did ever you know such a musty smell anywhere as there is about here? It can't be wholesome." Well now, if one goes on living a long time with a smell of that kind (I tell you it was worse than I ever knew it) it must get into the system and break out some time, don't you think ?'

The following winter brought an event no less strange than Wilbur's first trip outside the Dunwich region. Correspondence with the Widener Library at Harvard, the Bibliothèque Nationale in Paris, the British Museum, the University of Buenos Ayres, and the Library of Miskatonic University at Arkham had failed to get him the loan of a book he desperately wanted; so at length he set out in person, shabby, dirty, bearded, and uncouth of dialect, to consult the copy at Miskatonic, which was the nearest to him geographically. Almost eight feet tall, and carrying a cheap new valise from Osborne's general store, this dark and goatish gargoyle appeared one day in Arkham in quest of the dreaded volume kept under lock and key at the college library - the hideous Necronomicon of the mad Arab Abdul Alhazred in Olaus Wormius' Latin version, as printed in Spain in the seventeenth century. He had never seen a city before, but had no thought save to find his way to the university grounds; where indeed, he passed heedlessly by the great white-fanged watchdog that barked with unnatural fury and enmity, and tugged frantically at its stout chain.

Wilbur had with him the priceless but imperfect copy of Dr Dee's English version which his grandfather had bequeathed him, and upon receiving access to the Latin copy he at once began to collate the two texts with the aim of discovering a certain passage which would have come on the 751st page of his own defective volume. This much he could not civilly refrain from telling the librarian - the same erudite Henry Armitage (A.M. Miskatonic, Ph.D. Princeton, Litt.D. Johns Hopkins) who had once called at the farm, and who now politely plied him with questions. He was looking, he had to admit, for a kind of formula or incantation containing the frightful name Yog-Sothoth, and it puzzled him to find discrepancies, duplications, and ambiguities which made the matter of determination far from easy. As he copied the formula he finally chose, Dr Armitage looked involuntarily over his shoulder at the open pages; the left-hand one of which, in the Latin version, contained such monstrous threats to the peace and sanity of the world.

The universe (which others call the Library) is composed of an indefinite and perhaps infinite number of hexagonal galleries, with vast air shafts between, surrounded by very low railings. From any of the hexagons one can see, interminably, the upper and lower floors. The distribution of the galleries is invariable. Twenty shelves, five long shelves per side, cover all the sides except two; their height, which is the distance from floor to ceiling, scarcely exceeds that of a normal bookcase. One of the free sides leads to a narrow hallway which opens onto another gallery, identical to the first and to all the rest. To the left and right of the hallway there are two very small closets. In the first, one may sleep standing up; in the other, satisfy one's physical necessities. Also through here passes a spiral stairway, which sinks abysmally and soars upwards to remote distances. In the hallway there is a mirror which faithfully duplicates all appearances. Men usually infer from this mirror that the Library is not infinite (if it were, why this illusory duplication?); I prefer to dream that its polished surfaces represent and promise the infinite ... Light is provided by some spherical fruit which bear the name of lamps. There are two, transversally placed, in each hexagon. The light they emit is insufficient, incessant.
