I recently purchased the 128 volumes of the Official Records on a CD. Obviously, it is an indispensable tool. I just recently noticed that there was a supplement (100 Vol. ?) published in, I believe, 1998. Does anyone know how much of this supplement pertains to the trans-miss.? I would like to know whether or not it contains valuable information on the war in Mo. and Ar. before I pursue it further. Also, can it be purchased on disk or is it available online?
Please overlook my ignorance here, I am new to this type of research.
