See: How to Find Old Newspapers and Magazines Online
Now it's so simple to discover these age-old news stories - Google has made it possible to search across these rare and historica news archives through a new service called Google News Archives launched today.
The service lets you search across historical newspapers and magazines from 1754 to present. There are more than 120 million stories in the archives search index ["the" between 1754 to 2006]
Sources range from free news articles on ad-supported sites such as Time Warner Inc.'s Time.com and The Guardian or snippets of articles available for a fee or via subscription, from newspapers like The New York Times, the Wall Street Journal and the Washington Post.
I am now digging for immediate media reactions when Martin Luther King made his famous speech "I have a dream". If you are interested in history, this is one service that you should definitely bookmark.
