The British Museum says that more than 2000 items are missing from its collection and that 28 items have been stolen in recent years. “While the thefts represent a tiny fraction of the 150 million items in the library’s possession, the stolen items are valued at £100,000, with a number of rare maps and illustrated plates ripped from antique books by international thieves. A single plate cut from a 1522 volume on Pompeii is worth £45,000.”
