Hat tip to my colleague Joe Camisa for making me aware of this new site that links digital Civil War collections from a several prestigious libraries in the South. Civil War in the American South is a project put out by members of the Association of Southeastern Research Libraries (ASERL), which include libraries at Duke, Clemson, Kentucky, Louisiana, Mississippi State, Virginia, and the UNC system. A cursory glance shows several promising collections on a variety of subjects. I urge my readers to check it out and explore this research tool.
Thanks to the forums at the Company of Military Historians, there are a couple websites made known that provide online access to Civil War manuscripts. The first is Manuscripts of the Civil War: Diaries & Journals, which is affiliated with Notre Dame. The other site is called Civil War Manuscripts Project, which is part of the Connecticut Historical Society. If you are interested in researching, or simply reading Civil War manuscripts, then check these sites out.
