The Library of the Military History Institute in Prague has provided access to another 21 manuscripts from its collection, coming from between the end of the 17th century and the first half of the 20th century. The earliest part is mainly represented by theoretical treatises on military science and fortification technology. The chronicle from the military school in Hranice in Moravia (IIR G 413) comes from the turn of the 20th century. A more homogeneous group is formed by diaries and personal memoirs of the First World War (IIR C 13301, IIR D 3323, IIR F 642).
