The alternate Dewey Decimal System

In “The Haunter of the Dark” (1936), the unfortunate protagonist stumbles upon shelves of “mildewed, disintegrating books” — “the banned and dreaded repositories of equivocal secrets and immemorial formulae.” These include “a Latin version of the abhorred ‘Necronomicon,’ the sinister ‘Liber Ivonis,’ the infamous ‘Cultes des Goules’ of Comte d’Erlette, the ‘Unaussprechlichen Kulten’ of von Junzt, and old Ludvig Prinn’s hellish ‘De Vermis Mysteriis.’ ” The titular details — the sinister-looking double i’s in “Mysteriis,” the rebarbative German tag of von Junzt’s work — are arguably as chilling as the overwrought prose Lovecraft sometimes discharges.
