An intriguing story from CNN caught my eye tonight. It's about a library that straddles the US/Canadian border. People who park up in Quebec to return their Margaret Atwood have to cross the national boundary to enter through the front door, which happens to be in Vermont. Within the building itself, there's a line drawn across the floor. On one side, we presume the books are in French, while on the other they're in American. US federal authorities are now twitchy about the potential for illegal immigration.
