A short while ago I put a notice similar to this one on the Blog....and it was wrong...the referenced website was a pay site. So let me try again.
A while ago, the Library of Congress announced that "Chronicling America: Historic American Newspapers" is debuting with more than 226,000 pages of public-domain newspapers from California, Florida, Kentucky, New York, Utah, Virginia and the District of Columbia published between 1900 and 1910. The fully-searchable site is available at http://www.loc.gov/chroniclingamerica/.
When you reach that site, right in the middle of the screen will be a box labeled "Search Pages." If you click on that you will be taken to a search form and eventually to the image of the target newspaper.
