It’s World Book Day, at least in the UK, and the photos of kids dressed as their favorite literary characters are adorable and hilarious.

I am impressed by the guys who built the secret tunnel in Toronto, and even more impressed now that they’ve explained it wasn’t really a tunnel, just a hideaway place.

At UNC, they’re creating a digital sound archive of the civil rights movement, with broadcasts from radio stations of the time. This is a brilliant idea.
