I thought I found a pretty cool volume of books tonight. I was at a bookstore that specializes in publisher's overstock and used books where I came across volumes called "The War of Rebellion" by the National Historical Society. They had volumes 8, 10, 30, and a couple others as well as another set named "Official Records of the Union and Confederate Navies in the War of Rebellion" also by the National Historical Society. Each volume was about 1000 pages and covered a period of time in a certain theater. It contained copies of correspondence between officers as well as OOB and casualties for all units. Each book was $7.95, and some were still shrink-wrapped. I thought this was something special until I came home and googled this:
http://ehistory.osu.edu/uscw/library/or/index.cfm which appears to be a freely accessible version of the entire set.
Well this seemed interesting to me and I thought some others may find it that way too.
