In 2024, the National Technical Library in Prague provided access to one manuscript and nine printed book from its collections. The manuscript (shelf mark C 1178, system number 615616) was probably written at the turn of the 18th century and contains a collection of alchemical recipes. The printed books come from between 1645 and the early 19th century; the oldest (shelf mark F 11, system number 606794) was printed in Paris, the others in Germany. Most of them deal with the military and with fortification architecture.
