The “Taiwan Diary Knowledge Bank” (URL: http://taco.ith.sinica.edu.tw/tdk/) on a wiki platform is established by digital archives group at Institute of Taiwan History (ITH). Now it is online for test purpose, and regular researchers of Academia Sinica have access to it. Other users can use it at Historical Records Reading Room, ITH.

This database embodies useful and precious published dairies, including dairies of Chang Li-jun (1906-1937) and diaries of Lin Hsien-t'ang (1927-1940, dairies from 1941 to 1955 will soon be added one after another), inclusive of the full text and annotations attached to them. Users are able to browse the dairy articles by date, and perform full-text search.

Diaries are daily records of one feels and acts, and also the records of social change. They are important historical materials for studying personal history, family history, and the development of economy, society and politics.
