The bibliography of Mythos-related works given in the 'Call of Cthulhu' rules ends at about 1938.  Barring the intervention of some mysterious force or agency, there must have been at least *some* publications in the last half-century dealing, however peripherally, with the Great Old Ones. 

In fact, modern investigators may well stumble across either of the following modern tomes in the course of their researches.  Note that both are written in modern English, and as such do not require an Own Language roll for native English-speaking characters; this makes them slightly more potent, ounce-for-ounce, than archaic tomes.  Also note that these books have not existed long enough to develop the sort of reputation possessed by, say, the Black Book of von Junzt (or even 'People of the Monolith'); librarians won't look askance at investigators who ask about them - in fact, most librarians won't know they exist.

This obscure book was one of the few titles published by the ill-fated Human Horizons Press, which closed when its offices burned down in the early morning of May 1 (Beltane), 1983.  Research will disclose that the book's author, Jonathan Stellare, was arrested in connection with the fire, but committed suicide while in police custody.  The book never actually went to the printers before the fire, but bound galleys were sent to several reviewers.

Stellare appears to have had access to a mostly-complete copy of Dr. John Dee's English translation of the _Necronomicon_ in the preparation of this work.  He draws parallels between the rituals that Abd al-Azrad describes and algorithmic descriptions of computer programs.  Pseudocode and fragments of source code are included from one of Stellare's attempts to electronically re-create a worship service of the Outer Gods; a competent computer programmer who learned the spells from this book might be able to construct a program to aid in their casting (Keeper's option).

Unfortunately, Stellare does not appear to have truly understood the significance of the _Kitab Al-Azif_, and his explanations and descriptions are fragmentary, confused and heavily adulterated with New Age mysticism.


BEYOND THE VEILS OF SCIENCE
by "Dr. Harlo Y. Patten"; unpublished manuscript (1971)

BRP: Sanity loss 1D6/2D6; Cthulhu Mythos +11%; spell multiplier x1
Nemesis: necessary skills: Physics, Language [English], Difficulty: 2, Intensity 6, learning time: 5-width in days
(recommended spells: Create Gate, Call/Dismiss Azathoth).

This tome will fall into the investigators' hands in the form of a tattered photocopy of a low-quality dot-matrix printout.  The author's name is an obvious pseudonym (and an anagram of "Nyarlathotep"), and little or nothing is known about the book's true origins.

"Dr. Patten" presents a philosophical reflection on the meaning of modern physics, much like 'The Tao of Physics' or 'The Dancing Wu Li Masters', but informed with a sinister and oppressive Mythos sensibility.  The book discusses the implications of relativity, quantum mechanics and non-Euclidean geometry as a way of thinking about the world, and demonstrates that human notions of morality and ethics are meaningless in the face of an empty universe ruled by random chance.

Characters becoming temporarily or indefinitely insane as a result of reading this book will usually manifest their disturbance either as a chokingly deep and pervasive depression, or as a variant of Quixotism: "referential mania", the belief that everything that happens, no matter how small -- the blowing of a dead leaf across the street, someone slamming a door, the shapes of clouds -- has a darker, hidden meaning.
