Try writing to this man and see if he can help.
Brian Robertson<brianr@cals.lib.ar.us>
He is still at the Butler Center, I believe, and he can either assist or probably
tell you who can.
Brian was working on the Korean project last summer but I have no idea
where his focus is now. However, I do know that he is interested in the
Civil War and does read and post on this site ever so often.
Good luck.
Linda
