A 1615 Geneva Bible stolen two decades ago from the Carnegie Library in Pittsburgh in a long-running theft scheme has been recovered from a Dutch museum, the F.B.I. announced this week.

The Bible was among hundreds of rare books, maps and other items, worth about $8 million in total, that the authorities have said were stolen by the archivist in charge of the collection over nearly 20 years.

Prosecutors say the archivist, Gregory Priore, 62, sometimes walked out of the building with the items in plain sight. He then sold the works to a prominent book dealer, John Schulman, 55, whose shop was a block away and who had appeared as an expert appraiser on the television show “Antiques Roadshow,” according to an affidavit.

The two men were charged last year with numerous counts of theft, conspiracy and other charges, and await trial. Robert G. Del Greco Jr., a lawyer for Mr. Schulman, said his client maintained his innocence, but declined to comment otherwise. A lawyer for Mr. Priore did not immediately return a call on Friday.
