Taiwan National Treasure (TNT) is an online open database of Taiwan history for non-profit use. 

The mission of the TNT is to provide the Taiwanese with abundant historical  records and perspectives when reviewing the past based on information and records regarding Taiwanese society, geography and figures collected by the U.K., U.S., and other countries over  one hundred years. Those historical materials are open to all people through the public database. Hence, the stories in Taiwan could be revised by combining multiple aspects. The TNT team has developed a system with features of volunteers’ collecting contribution and the online database. TNT also calls for volunteers via social media to participate in document collection activities onsite at the U.S. National Archives and Records Administration. 

The TNT has collected more than 200,000 Taiwan-related documents and images from the U.S. National Archives and Records Administration -NARA II). Most of them are federal documents, some are investigation into conditions of the society, and the rest are images from newspapers and magazines. The time period covers from the Japanese colonial rule to the cessation of normal diplomatic relations between the U.S. and the R.O.C. and the content includes international events and social records in terms of politics, military affairs, news, education, culture, economics and trade, agriculture and so on.
