National Review's "The Corner" pointed me to this article and quote in The New York Times:

Michelle Campbell, 26, a librarian in Washington, said that librarianship is a haven for left-wing social engagement, which is particularly appealing to the young librarians she knows. “Especially those of us who graduated around the same time as the Patriot Act,” Ms. Campbell said. “We see what happens when information is restricted.”

The first thing that comes into my mind: "What's your phone number? Home address? When do you get off work?"

I'm thinking that there's a possibility that that information might be restricted.
