This is kind of a shot in the dark, but... I was reading an article in The New Yorker at the gym (it was a couple of months old), about rare books thefts. I used to work in a rare books library that *had* been hit by a map thief, so I was pretty interested. In the article, it mentioned that in the 1970's, "byzantine monks" had gone to the Yale library, and stole books hiding them under their cassocks (!) When the monastery library was searched, it was apparently full of stolen books. Has anyone ever heard of this? I have no idea whether the author meant Orthodox monks, Byzantine Catholic monks, whatever. I couldn't find anything online though, so I thought I'd try here. Very strange, to say the least.
