Go to www.mississippiscv.org and click on "Research Help" for several good research aids. See also "Mississippi Regimetnal Histories" (or something similar) at "Research Help."
In the updated Dornbusch (bibliography of War for Southern Independence units), I note this entry:
"Muster Rolll, 32nd Mississippi Infantry, C.S.A., compiled by Tommy Lockhart, Ripley, MS, Old Timer Press, 1982 [conjectural date], 224 pp."
This, it would seem, is more than just a simple listing of soldiers.
