This report presents the results of wood species identification on 1,086 Nguyen Dynasty woodblocks sampled from books currently stored at the National Archives Center IV, The State Records and Archives Department of Vietnam. The study identified 02 species of wood (Thuc Qua wood and Thi wood) used to make Nguyen Dynasty woodblocks. Preliminary assessment results showed that both species of wood are susceptible to fungal attack. However, under current storage environmental conditions (RH <65%) will limit the growth of fungi. In addition, the woodblocks are made from wood that is hundreds of years old, so the wood has basically reached a state of balance and stability. Therefore, it is possible to preserve woodblocks made from 02 types of wood under the same storage environmental parameters.
