Their website says "The largest online newspaper archive", while I haven't had to stray too far around the planet to find newspaper articles I must recommend subscribing to this on-line newspaper archive. As of today, I have found 500+ articles concerning my ancestors!
Creator: Newspapers.com (iArchives Inc., previously Automated Solutions Inc.) was acquired by Ancestry
Published: Beginning 2010, Utah, USA
Author: Various
From their website, "Newspapers.com is the largest online newspaper archive consisting of 634 million+ pages of historical newspapers from 20,100+ newspapers from around the United States and beyond."
Newspapers.com is a subscription resource. If you use the site in conjunction with an Ancestry.com or Ancestry.ca subscription you will be able to gain access to their searches in a very efficient fashion. The site can also be used on it's own.
Before I subscribed to the site I thought I was doing pretty well with finding newspaper articles. Through using microfilm and the Google News Archive I had found 150+ articles. After I subscribed to Newspapers.com I was able to find an additional 560+ articles in less than a year. To me it has been of tremendous value in my search.
Go to the site and plug in your ancestors names and places!
