1. Doctoral dissertations and master's theses are located at the Dah Hsian Seetoo Library. The call number of doctoral dissertations includes a “D” to differentiate them; e.g.,Ｄ1.11, 1.11 are displayed on the 1.11 shelf. Readers must notice, however, that the call number of doctoral dissertations has a “D” added at the beginning.
2. NCCU theses and dissertations are located on the receding terrace shelves from 5th to 7th floor.
3. Theses and dissertations from other colleges held in compact shelves. All materials are accessible through closed stacks retrieval services.

In accordance with Article 16 of the amended Degree Authorization Act, the National Central Library is the only depository library for doctoral dissertations and master's theses in the country. Hence, beginning in 1997, some universities have not presented free copies of dissertations to NCCU:

1. National Taiwan University: up till 1997.
2. National Tsinghua University: up till 1995.
3. Soochow University: up till 1996.
4. Tunghai University: up till 1997.
5. National Sun Yat-Sen University: up till 1997.
6. Providence University: Incomplete collection since 1997. Did not present free dissertations in 1998. Reverted to presenting dissertations in 1999.
7. Tamkang University: up till 1998.

In consideration of the trend of collection and digitization development, and the National Central Library's collection of national theses & dissertations, NCCU Library has stopped collecting dissertations and theses of other universities.

Q4. Why does the "National Digital Library of Theses and Dissertations in Taiwan" (NDLTD in Taiwan) of National Central Library have this dissertation, but I can't locate it in the Dah Hsian Seetoo Library, even the catalog of NCCU library?
