From Nichola Basbanes interview on Booknotes:

“… there are some humorous aspects to this [Stephen Blumberg’s book stealing spree]. During the trial, one expert testified about a book they called the bishop's Bible, and they believe--because when he acquired books, he also removed all traces of prior ownership, making identification difficult. Where do the books belong? Where should they go back to? But on this bishop's Bible case, they said, `Well, he took this from Rice University.' Well, I mean, when that was reported in the AP the next morning, that's the first that those people knew that--that was the first time they knew that book was missing. Fully 95 percent of the books that he stole were not known to be missing until these people were notified by the FBI.“
