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.[1]


Books with paranormal properties are often referred to as "Leitners" whether or not they were actually in his library. 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".[2] Robert Smirke called them "secret" books.[3]

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).[1]

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.[1]

Some of the books can be destroyed by means such as burning[4] while others resist attempts at destruction.[5] 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.[6]

John also mentions that "all" of the books from the library are custom editions of known texts on dæmonology or the arcane in,[4] though this idea has not held in canon, with books that would have been known to him and the Institute at that time such as DIG.
