Journal articles in history are divided geographically between two major databases: America: History & Life covers journal articles about the United States and Canada, and Historical Abstracts covers journal literature for world history outside the U.S. and Canada, 1450-present. Don't forget that books are the most important publishing format for historians, so don't stop with journal articles in your research!
The Center for Research Libraries (CRL) is another excellent resource for books, periodicals, manuscripts, newspapers, and archival materials in print, microfilm, and digital formats. FSU belongs to this international consortium of university, college, and independent research libraries, which allows FSU patrons to borrow CRL materials via interlibrary loan for extended periods.
One way to identify key collections is through CRL Topic Guides.
