Necronomicon

(Did you mean a apa or conventions in Florida, Massachusetts, Rhode Island or London?)

A forbidden book from the Lovecraft mythos.

Owlswick Press published a small edition of the Necronomicon as its first volume in 1973. It was apparently ghost-written (how else?) by L. Sprague de Camp, but consisted entirely of Arabic script. The Library of Congress balked at registering the copyright on the grounds that it was a reprint…

Abdul Alhazred's handy guide to demonology, in the Lovecraft mythos. All fulla dread secrets and tales of the Elder Gods, not to mention darker Hints about the Universe. Rare as it is, many a pallid, sensitive young intellectual has come to a messy end by study of its direly blasphemous pronouncements. (Many collectors have gone digging around in libraries for it, but actually the nearest thing to such a volume is the grimoire, several of which were written by medievals. The index-cards you'll find in the files of the Library at Yale University ["In rare book collection… bound in leather believed human"] turned out to be a hoax.) Only a meagre portion of the text has wide circulation; bibliophile Coswal, cautioning against fakes, explains that the only genuine Necronomicon quotes are those forged by H P Lovecraft. All other forgeries are imitations.

Necronomicon apparently was used as a name for the league organization sponsored by Weird Tales, from which the Washington Outsiders descended.

(Lovecraft) - A book by Alhazred, the mad Arab, full of dread secrets and tales of the Elder Gods, and darker hints, which Lovecraft often referred to in his stories. Many collectors have gone digging around in libraries for it, but it actually does not exist, the nearest thing to it being some shadowy books by medievals. Necronomicon apparently was used as a name for the league organization sponsored by Weird Tales, from which the Outsiders' Club is descended. We append an incantation to Yog-Sothoth, taken from the Necronomicon: "Ygnaiih - ygnaiih - thflthkh'ngha - Yog-Sothoth - y'bthuk h'ehye - n'grkdl'lh."
