"... this microfiche collection has attempted a comprehensive filming of all ... monographic histories listed in C.E. Dornbusch's Military Bibliography of the Civil War, Volumes I and II: Regimental Publications and Personal Narratives of the Civil War ... In order to preserve the subject and organizational integrity of this microfiche collection, individual volumes from larger sets were generally avoided, as were monographs which only dwelt in small part with the Civil War experience. Many memoirs fell into the latter category. In addition memorials of deceased officers and men as well as unit rosters were usually excluded." -- Guide, unit 1, p. i.
