The Google News Archive chart http://news.google.com/newspapers/ is very useful but needed to be enhanced by adding the name of country or state where the newspaper was published. I completed that task and put the name of where the paper came from.
That being done, I thought the list was too large to review since there were lots of newspapers published in Canada and other countries, so I removed all those newspapers from this new chart. This new chart only has the newspapers which are published in The United States. The names of the fifty (50) States plus DC are on top of the chart so you can pick the name of the State you want to see and you will be taken to the collection of those newspapers. When you want to go back up to the list of states you can click on "Back to Top" which is at right of chart.

I hope you will find this chart useful for your searches of news stories about your family tree ancestors.
Thank You
