Next week, Americans with digital cameras and "a passion for telling stories with pictures" are invited to contribute to America 24-7, "a one week digital time capsule of American life". 10,000 of the best photos snapped between 12:01 AM on Monday, May 12th and midnight on Sunday, May 18th will be included in TV documentaries, photo exhibitions, an "engaging website" and be published in 53 large-format books by DK -- one national volume and one for each state plus New York City and Washington, D.C. Start charging those batteries.
