In 2023, the National Technical Library provided access to one manuscript and a set of seven German-language printed books from the end of the 18th century and the beginning of the 19th century. The manuscript (shelf mark C 1175) dates from about 1761, bears the title Clavis artis and contains alchemical instructions attributed to Zoroaster. Under the shelf mark B 100, there is a set of engravings accompanying three text volumes of Der praktische Baubeamte, printed in Vienna in approximately 1797–1798. The other printed books come mainly from Germany and deal with various branches of industry and trade.
