Where to find dissertations and theses?


A thesis or dissertation is the paper required for completing a diploma.  Theses and dissertations could help us understand the research outcome of the department and senior students, and the analysis of sources and references could help us familiarize ourselves with the development of research in the past.  If you were not sure about what issues your thesis will delve into, what topics you are considering had other students studied, and with what emphasis and precedent research, you may begin with the theses and dissertations written by other students.

Generally, theses and dissertations are not officially published, thus making them difficult to obtain from a typical bookselling platform. They are usually collected in the National Central Library and the library of the university to which the author of the papers belong. One could only access the full text if the author’s thesis or dissertation is authorized. So, which databases can users search for master’s thesis and doctoral dissertation?


【National Taiwan University】

  1. NTU Theses and Dissertations Repository (NTUTDR): It collects information and full text of theses and dissertations since 1963 (according to the author’s authorization).
  2. Airiti Library: The database contains the digital version of theses and dissertations, and the collection is called “Chinese E-Theses & Dissertations Service”.
  3. If there is no digital version of the thesis or dissertation, please check NTU Library’s SLIM system to find the printed version.
