You will need to select keywords to describe your topic and enter the keywords into the search boxes. Try a combination of keyword searches. The Historical Newspaper databases do not work well if you try to search for a long phrase.
For example, Speech by Booker T. Washington at the Cotton States and International Exposition in Atlanta. Try entering Booker T. Washington in the first search box. Enter cotton states in the second search box. Enter speech or address in the third search box. This may yield one set of results.
