This Library of Congress site features digitized newspapers from across the U.S., 1836-1922, including 137 Mississippi titles (but not every issue!). Select "Mississippi" from the pull-down menu, "All States."
This database has a vast collection of African American newspapers, but is limited in scope for Mississippi with only 6 titles. Of note, it contains all 117 issues of the Mississippi Free Press, 1961-64.
If you're looking for a specific MS newspaper and can't find it, MDAH probably has it. Visit their archives in-person or pay for reproduction of articles (not recommended unless you know exactly what you need). More on reproduction costs: http://goo.gl/hSd5jP
