MSNBC.com has this story about a Wisconsin woman who failed to return two books in a timely fashion to her local public library, and paid no attention to its sad entreaties about their overdue status. The result: the librarians flexed their muscle, called out local law enforcement, and had her arrested and booked for failure to pay fines and overdues. No joke: this little episode cost her and her family several hundred dollars. The books? They were appropriately law-related: Janet Fitch's White Oleander and Dan Brown's Angels and Demons. The moral? Spider Robinson puts it best.
"Librarians are the secret masters of the universe. They control information. Never piss one off."
