Google has announced that it intends to put all the newspapers in the whole wide world that have been published in the past 200 years online and searchable. You go, Google! As an example, they show an original article from a 1969 edition of the Pittsburgh Post-Gazette about the first man on the moon. To explore this "historical treasure trove" search the Google News Archive or use the "timeline" feature after searching Google News.
But note that "this effort is just the beginning".
