Since beginning of the 20th century, a certain number of the Tangut literatures were discovered in the north part of the Dunhuang Mogao Caves. Although most of them belong to fragments, it is wothy to give special attention. Besides manuscripts, the Tangut also has wood block and movable types from hard clay. Detailed descriptions are given to the important materials, such as civil documents (including contracts, account books etc.), dictionaries (including Sui - jin 碎金, San - jiu - za -zi三九雜字, and Fan - han - he - shi - zhang - zhong - zhu 蕃漢 合時掌中珠) and religious texts, including Buddhist and Daoist canons and others.
