Department of Chinese Literature, National Taipei University, has been promoting the Chinese digitalized application. In these years, we have established a variety of literary and historical systems for the scholars and researchers’ reference. "Signet Database of the Rare Old Books in National Central Library" is the latest developed literary and historical system and the three-year project subsidies have been approved by Ministry of Science and Technology. The system aims at the rare old books signets collected by National Central Library, Taipei, expecting to effectively examine the collecting process of the library and make statistics about the number and features of the book collectors. At the same time, all kinds of the collected information will serve as the reference for scholars. This article will first have an introduction to the purpose of the establishment and clarify the future prospect. The system establishment will be completed by April 2017 and open to readers for examination and application.
