How many books can you buy with $8 million? A lot, but the Carnegie Library of Pittsburgh didn’t notice any of their collection was gone until a 2017 appraisal showed that a few listed in the collection in a 1991 appraisal were no longer there. The books were kept in the library’s Oliver Special Collections Room. Archivist Gregory Priore had been manager of the Special Collections Room since 1992. He arranged appointments, granted access and supervised visits for scholars and others. Visitors had to store their personal items in a locker before entering the room.

It took only four days for the appraisers to notice a problem. The room was closed, the locks were changed and Priore was denied access. Several of the very rare books were traced to the Caliban Book Shop. Priore had been stealing the books and John Schulman, an owner of the book shop, had been selling them. The missing books were found online, in ads and in past auctions. Some illustrations, pictures and maps (known in the book world as “plates”) were removed and sold separately. Books worth over $1,150,000 have been recovered. One, a 1787 book signed by Thomas Jefferson, was being offered for sale for $95,000. But some are still missing, and the lost value of the library’s collection is estimated at more than $8 million, one of the largest book thefts ever. The two men are scheduled for trial, with hearings starting in August. They are charged with 30 crimes including theft, library theft, conspiracy, forgery, receiving stolen property, criminal mischief, and deceptive and fraudulent business practices.
