There is a great online collection of historic newspapers hosted by the Library of Congress called Chronicling America: Historic American Newspapers. The newspapers are from 1880-1922 and make for a fascinating glimpse into the past. The classic advertisements are just as interesting as the stories themselves. The newspapers are easy to search by name, keyword and date. The excellent presentation of the scanned newspapers allows you to zoom in and out, view as a PDF, download and print.
