Interlibrary loans, said Alison Macrina, founder and director of the Library Freedom Project, form an ad-hoc record of departures from regular patterns of lending – the kind of thing that often interests intelligence and law enforcement analysts.

“It seems like it’s a more interesting data trail,” said Macrina. “It’s a book you wanted so bad that you went to special lengths to get it, and we know how intelligence agencies pay attention to breaks in patterns.” Macrina hadn’t heard about the CUNY Graduate Center initiative, but said it was a relief to her. “It’s taken a little too long but I’m really glad to see it’s happening somewhere.”
