Google News Timeline is a web application that organizes search results chronologically. It allows users to view news and other data sources on a browsable, graphical timeline. Available data sources include recent and historical news, scanned newspapers and magazines, blog posts, sports scores, and information about various types of media, like music albums and movies.

I observe the absence of "century" and "millennium" modes. It sadly informs me that "0 is not a valid date." Apparently nothing newsworthy happened in 1401. Ditto for 1425.

It would be nice if they could present the Google Books data with this interface.
