War of the Rebellion: Official Records of the Union and Confederate Armies

This is the basic source for the Civil War, 128 volumes, serial 1-130. Cost for a complete new series is about $2,650.00 & is sometimes sold with the 52 volume set of the Southern Historical Society Papers as a freebie. If you are a serious Civil War historian or only a buff, SPEND THE MONEY! Yes, most university libraries have these sets, but many public libraries do not. Personally I could not live without this set on my shelf when doing research.
