The Library of Congress’s Chronicling America website has lists of newspapers, searchable and navigable by title, as well as tens of thousands of images of newspapers from 1880 to 1922 from 15 states (plus the District of Columbia):
- Arizona
- California
- District of Columbia
- Florida
- Hawaii
- Kentucky
- Minnesota
- Missouri
- Nebraska
- New York
- Ohio
- Pennsylvania
- Texas
- Utah
- Virginia, and
- Washington.
The site catalog is very handy for finding out about local newspapers that might be available through inter-library loan (ILL) on microfilm and by other means in libraries across the country.
You can even predict the URL for a county you are interested in. For example, the URL for Monroe County, West Virginia is:
http://chroniclingamerica.loc.gov/titles/places/west%20virginia/monroe/
And the URL for Valley County, Nebraska is:
http://chroniclingamerica.loc.gov/titles/places/nebraska/valley/
So, the pattern comes down to:
Prefix: http://chroniclingamerica.loc.gov/titles/places/ [which, itself is not a workable URL]
To this, you append the state, a slash, then the county, and a slash.
State (with spaces replaced by %20, the HTML code for a space): some%20state/
County (with spaces replaced by %20, the HTML code for a space): some%county/
Happy hunting!
