Which Sources Does Google News Index?

Google tells us they index ?more than 4,500 English-language news sources worldwide? in Google News USA. Which could mean any number, really... and we know they add new sources all the time. To find out how much (and what) they really index, for the past days I polled roughly 1,4 million news stories per day by searching Google News for semi-random words every few minutes. I found over 8,600 unique news sources in Google News and made them available for sorting & searching.
