The Digital Library of Georgia announced last week the addition of the Athens Historic Newspapers Archive, which consists of five newspaper titles published in Athens from 1827 to 1922. The collection has over 57,000 pages and is available at http://dlg.galileo.usg.edu/athnewspapers.
You will need the DjVu plugin to view the site. You can browse by title/year or do a keyword search. I did a full search for Carriage and got 8570 results. Results included name and date on the paper and how many matches for your keyword were on a full page.
Click on the result and you’ll get the full page for browsing, but if you don’t have the DjVu plugin you won’t be able to see anything, so make sure you get that before you start your search!
The Digital Library of Georgia has several great newspaper collections. You can get a rundown of what’s available at http://dlg.galileo.usg.edu/MediaTypes/Newspapers.html.
