List of books

This is a list of paranormal books that have been mentioned or encountered. It is not yet known how many of these books exist in the world, although Jurgen Leitner mentioned having 978 in his library at its height.MAG 80: The Librarian
==Overview==
Due to Leitner very proudly pasting bookplates inscribed with "From the library of Jurgen Leitner" into every book he owned, books with paranormal properties are often referred to as "Leitners" whether or not they were actually ever in his possession. It is unclear if they were referred to as something else before him, or if they were thought of as "each one a thing unto itself".MAG 62: First Edition Robert Smirke called them "secret" books.MAG 138: The Architecture of Fear
In general, the books are more powerful than any other supernatural artefacts, though individual books may range from "innocuous" to "unsettling" to "murderous". Leitner refers to them as "the essences of The Entities in a purer form"; they generally only correspond to a single entity (with some exceptions such as the Key of Solomon).
They frequently have unusual interactions with architecture that was either designed by Robert Smirke or based on his principles of balance. It seems to stabilize their effects to a degree and allows for safer storage.
Some of the books can be destroyed by means such as burningMAG 4: Page Turner while others resist attempts at destruction.MAG 70: Book of the Dead Leitner hypothesized that some (likely those affiliated with The Desolation) even liked the flames, and upon burning would be "released to take a different form". Jonathan Sims similarly theorized that attempting to rip a book of The Slaughter in half may have intensified its effects.MAG 125: Civilian Casualties
John also mentions that "all" of the books from the library are custom editions of known texts on dæmonology or the arcane, though this idea has not recurred in the canon, with books that would have been known to him and the Institute at that time such as DIG?

Name 	Description 	Entity 	Notes
A Disappearance 	A pamphlet that causes the reader to disappear without a trace if read in its entirety.MAG 158: Panopticon The entity it is aligned with is never revealed, but given that members of the Lukas Family possess a very similar ability, The Lonely seems a likely possibility. If only a small part is read, it will hide the reader from others for a short period of time, as Jurgen Leitner discovered. 	The Lonely 	
A Guest for Mr. Spider 	A picture book tied to The Web that entrances its reader and leads them to be taken by Mr. Spider.MAG 81: A Guest For Mr. SpiderMag 160: The Eye Opens 	The Web 	
A Journal of the Plague Year 	A version of Daniel Defoe’s A Journal of the Plague Year which spreads infection. The entity it is aligned with is never explicitly revealed, but given its themes of disease, it is almost certainly connected to The Corruption.MAG 91: The Coming Storm 	The Corruption 	
An Introduction to Higher Anatomy 	Part of the "Yousuf case", which caused Daisy Tonner and Basira Hussain to be familiar with Leitner by name.MAG 92: Nothing Beside Remains No other information on the book or its effects are given. 	Unknown affiliation

Possibly the Vast 	Speculative title
Book of the Dead 	An old black book that fills, in blank pages, the date of and details for the death of the reader.

Most recently owned by Trevor Herbert and Julia Montauk.MAG 111: Family Business 	The End 	
Dictionnaire Infernal 	A paranormal version of the book by Jacques de Plancy. Sought after by Michael Crew in 1998 ("the older the better") and a copy purchased from Lion Street Books.MAG 46: Literary Heights 	Unknown affiliation

Ex Altiora 	Aligned with The Vast and inspires feelings of vertigo. Used by Michael Crew in 1998 to bind the Lichtenberg-figure creature stalking him, after which it begins to emit the smell of ozone. It is purchased by Dominic Swain and subsequently destroyed by Gerard Keay in 2012. 	The Vast 	
Key of Solomon 	A paranormal version of the fourteenth century book. It had been previously owned by MacGregor Mathers. Purchased on eBay by Gertrude Robinson in 2007 and destroyed by her and Jurgen Leitner in 2015. Leitner states that it was one of the very few books that was connected to multiple entities, though he does not specify which ones. MAG 66: Held in Customs 	Multiple 	
Unknown spider book 	A book connected to The Web that supposedly inspired the 1960s film 蜘蛛が食べている (kumo ga tabete iru), translated as "Spiders Are Eating”.

Memory Book 	Sasha James at one point had to experiment with writing in the Memory Book during her time as a practical researcher. Stored in the Magnus Institute artefact storage.MAG 39: Infestation No other description of the book or its effects are given, but considering Sasha was tasked with writing in it, there is a possibility it was some kind of journal. 	Unknown affiliation 	
Old crumbling book with no library markings	Found by Allan Schrieber, a friend of Elias Bouchard. All the pages appear blank but Elias sees them with faces on them in his dreams. Allan tells Elias that something without eyes "saw him" though the pages and seemed to have hunted him down, killed him, and stolen his eyes after reading it. The entity it is aligned with is never revealed, but there are two likely possibilities; The Eye, given that Allan was certain that something specifically "saw him," or The Dark, given that Allan's eyes were stolen.MAG 193: A Stern Look	Possibly The Eye/The Dark 	Speculative title
Sanskrit poetry book about dead animals 	Small animal bones fall from the book when passed through shadow. The bones are "slightly bent and warped into shapes that bones should not form". "Quite unremarkable" according to Mary Keay and sold by her to Jurgen Leitner. Eventually returned to her after the library attack when stolen from under Reform Club by Gerard Keay in 2002. Last seen in November 2012, in the possession of Mary Keay at Pinhole books.MAG 35: Old Passages 	Possibly The Flesh/The End 	Speculative title
Security Camera Instruction Manual 	An instruction manual for a security camera aligned with The Eye that has images of its readers within it. After reading it extensively, the reader becomes part of the security system, every camera feeling like an eye of the reader looking back at them. If read too extensively, the manual leads to a disastrous end for its readers.MAG 148: Extended Surveillance 	The Eye 	Speculative title
The Seven Lamps of Architecture 	A book by John Ruskin which gives a sense of walls pressing in around the reader, and may physically entomb them. It interacts differently with Robert Smirke's architecture. Reading it while in a building designed by Smirke allows the reader to control its architecture. The entity it is aligned with is never explicitly revealed, but the description of its effect is very similar to descriptions of claustrophobia, making The Buried a likely possibility. 	Possibly The Buried 	
Slaughter book 	An old and worn paperback aligned with The Slaughter that caused every resident of Lanncraig, Ross-Shire to brutally murder each other. Was found ripped in half with its pages blank and it is speculated that the tearing may have intensified the release of its power.MAG 125: Civilian Casualties 	The Slaughter 	Speculative title
Small book bound in red 	A small, red book that is connected in some way to The Cult of the Lightless Flame. Its exact effect unknown, and was last seen in the possession of Diego Molina in December 2011. The entity it is aligned with was never revealed, but given its connection with The Cult of the Lightless Flame, The Desolation seems the most likely possibility.MAG 12: First AidMAG 43: Section 31 	Possibly The Desolation 	Speculative title
Small grey book 	A small grey book, possibly in Cyrillic script, that is described as "trying to read [its reader] back." It was buried in a stretch of moorland by Michael Crew. While it is never explicitly stated, this book is most likely aligned with The Eye. 	Possibly The Eye 	Speculative title
The Stalwart Hunters' Almanac 	A leather-bound book that appears to cause mutilation of reader corresponding to the passages read. The entity it is aligned with is never revealed, but given the effect of mutilation, it is likely connected to either The Hunt or The Slaughter, if not both. 	Possibly The Hunt/The Slaughter 	
The Tale of a Field Hospital 	A supernatural draft copy of the book by Sir Frederick Treeves. Paper cuts from its pages appear to cause death via rapid infection, and the book contains passages regarding the exploits of one Private Amherst. The book was delivered to the Magnus Institute by Joseph Russo along with his statement, and subsequently destroyed via burning by Gertrude Robinson.MAG 68: The Tale of a Field Hospital 	The Corruption 	
The Travels 	A book responsible for the death of someone named Mr. Hampton that was presumably burned by Gerard Keay. Though never confirmed, it may be a paranormal version of A Masterpiece to Those Who Contemplate the Wonders of Cities and the Marvels of Traveling by Ibn Battuta, which is often referred to simply as "The Travels."MAG 162: A Cosy Cabin 	Unknown affiliation
