Private auctions, encrypted channels, estate vultures, institutional theft, forgery rings that reach the Vatican. The rare book world operates like organized crime because it might actually be organized crime — just quieter, older, and better dressed.
The market
A first edition Gutenberg Bible last sold for $5.4 million. A copy of the Bay Psalm Book — the first book printed in British North America — sold for $14.2 million. The Codex Leicester, Leonardo da Vinci’s notebook, sold to Bill Gates for $30.8 million. These are the legal transactions. The illegal ones don’t have public prices because they don’t have public records.
The rare book market is estimated at $2–5 billion annually. The unrecorded fraction — private sales, estate acquisitions, institutional deaccessioning, theft — is unknown by definition. The market’s opacity might not be a flaw. It might be a feature. Provenance gaps seem to be where the money is.
The forgers
Marino Massimo De Caro was the director of the Girolamini library in Naples. He stole over 4,000 volumes, including works by Galileo, Copernicus, and Machiavelli. He forged provenance documents. He sold to private collectors who didn’t ask questions because asking questions would reduce the value of the answers. The forgery ring reached the Vatican Library. He was convicted in 2013.
Mark Hofmann forged documents that challenged the founding narratives of the Mormon Church, sold them to the Church itself, and when his scheme began to unravel, built pipe bombs. He killed two people. His forgeries were good enough that they fooled the FBI’s document examiners, the Church’s own historians, and multiple academic experts. He’s currently serving a life sentence. Some of his forgeries might still be in circulation because identifying them would require admitting that the authentication process failed.
The collectors
The psychology of the rare book collector seems specific. It might not be about reading. Most serious collectors don’t read their acquisitions — reading damages the binding, cracks the spine, introduces oils from the hands. It seems to be about possession of a specific physical object with a specific history. The book isn’t a text. It’s an artifact. The collector wants the object that Galileo held, not the words that Galileo wrote. The words are available in any modern edition. The object is unique.
This psychology might create the market conditions for everything else. The collector who wants the object — not the text — will pay a premium for provenance. And provenance is the easiest thing to forge, because provenance is a story, and stories are what forgers sell.
Why this matters for Strange Library
The Harlan Collection is a private lending library in an unremarkable terraced house. The previous librarian, Marion, kept detailed notes on every acquisition — where it came from, who sold it, what condition it arrived in, what she noticed about the seller. Those notes are the game’s primary narrative device. They’re also, the player gradually realizes, evidence of Marion’s participation in a network that spans flea markets, estate sales, night auctions, private collections, and at least one person who is almost certainly a forger.
The rare book underground is real. The game builds on it. The fiction isn’t that this world exists — it does. The fiction is that you have the key to the front door.
