What are Doctoral Dissertations?

Doctoral dissertations are academic theses submitted to obtain doctorate degrees. Doctoral dissertations are stored and made available as follows:
  • Held by libraries at the university where the thesis was submitted
  • Held by the national library of the respective country (in Japan’s case, the National Diet Library)
  • Made available at no charge on the respective university’s Web site (institutional repository).
  • Sold as a book
  • Sold by specialized vendors (primarily North American doctoral dissertations)


Doctoral Dissertations at Waseda

Waseda doctoral dissertations are stored at the Honjo Deposit Library (in Honjo campus) and nearly all are searchable online from WINE. Doctoral dissertations submitted to Waseda University after 2013 are available at Waseda University Repository in principal. Some of the dissertations submitted after 2002 and agreed to be public by authors are also available there. Book forms must be sent to the Central Library or campus libraries from the Honjo Deposit Library. See How to Search and Use Waseda Doctoral Dissertations for more details. In case you prefer to glance through the dissertations' abstract/title of each graduate school, please consult the respective graduate school office. For dissertations the author permitted to be on public online, the index list of each graduate school is available at Waseda University Repository.



Doctoral Dissertations at Other Domestic Universities

Searching other university library

You can find doctoral dissertations submitted to other universities using respective university’s collection catalogs or doctoral dissertation search systems. In principal, Japanese doctoral dissertations submitted after April 1st, 2013 are supposed to be published on the internet, according to the revision of the Rules for Degrees by Japanese government (Doctoral dissertations submitted before April, 2013 are also available online if the authors agreed to open it to public). If the dissertation is not available online, you may consider visiting other university library or requesting a photocopy. Be sure to confirm the usage conditions on the respective university’s (library’s) Web site before visiting other universities. In most cases, a letter of introduction or an advance inquiry is necessary. In case of requesting a photocopy of a dissertation, it must be less than half of total pages due to the copyright. To copy more than half of the total pages, obtaining consent from the copyright holder is required in most cases.
