GUY RAZ, HOST:
From NPR News, this is ALL THINGS CONSIDERED. I'm Guy Raz.
ROBERT SIEGEL, HOST:
I'm Robert Siegel. It's time now for your letters. And we're going to re-visit perhaps the most ear-catching phrase heard on this week's program.
KIMBERLY DOZIER: Ninja Librarians.
SIEGEL: Ninja Librarians. That's Associated Press reporter Kimberly Dozier, talking about the people the CIA has brought in to comb through as many as five million Facebook messages and tweets a day.
DOZIER: You're talking about several hundred staffers. You've got people who are experts at finding information. A lot of them have Masters of Librarian Science. They know how to track things down on the Internet that you and I simply wouldn't know existed.
RAZ: Well, listener Sasun Baylik(ph) of Bellevue, Washington, has been trying to get a job as a librarian and writes: The degree is called a Master's of Library Science, not Librarian Science.
SIEGEL: Well, we ran this by our own ninja librarian, Mary Glendinning.
RAZ: It was hard to find her because she was wearing all-black.
SIEGEL: And Mary said this, Masters of Librarian Science is wrong. However, there are many names for this type of degree: Master of Library Science, Master of Arts, Master of Librarianship, Master of Library and Information Studies, and Master of Science.
RAZ: And then, Mary shimmied up the newsroom wall like a spider.
SIEGEL: Never mess with a ninja librarian. They'll correct you within an inch of your life.
