In 2021, the Military History Institute Prague provided access to 28 manuscripts, mostly from the 19th century. In terms of content, the texts are quite varied, consisting of personal notes and memoirs (shelf mark IIR B 2233, IIR B 2325, IIR C 16910, IIR C 3749), short encomiastic poems and texts, works on various military operations and campaigns or on military construction, manuals especially on firearms and artillery (including a work on gunpowder by Carl Heinrich Riegel in IIR F 1627), treatises on cavalry exercises compiled by Franz Philipp von Lamberg and Ignaz Ludwig Paul von Lederer, and others. Historiographical works are represented e.g. by a copy of the Latin biography of Albrecht von Wallenstein by Václav Vojtěch Červenka of Věžnov (IIR F 526) and the history of the Austrian Dragoon Regiment Prinz Eugen von Savoyen by Friedrich La Croix de Laval (IIR F 546). Some of the writings are accompanied by illustrations. The pictorial component predominates in IIR B 2326 (depicting the facings and uniforms of Austrian soldiers) and in IIR B 3827 (depicting naval flags).
