" The perfect Librarian is calm, cool, collected, intelligent, multilingual, a crack shot, a martial artist, an Olympic-level runner (at both the sprint and marathon), a good swimmer, an expert thief, and a genius con artist. They can steal a dozen books from a top-security strongbox in the morning, discuss literature all afternoon, have dinner with the cream of society in the evening, and then stay up until midnight dancing, before stealing some more interesting tomes at three a.m. That's what a perfect Librarian would do. In practice, most Librarians would rather spend their time reading a good book. "
