The landing page of this site provides you an interactive map to help show you the communities covered in its collection of small town newspapers. The collection is actually a collection of links to community libraries among others that have digitized collections.
The interactive map is a bit messy with an abundance of push pins. Another way to browse the collection is to click on the name of your state of interest in the list to the left of the map, and then follow the link to the city of interest.
This is a great site!
