Assigning DOI (Digital Object Identifier) to Doctoral Dissertations

Since April 2017, the University of Tsukuba's Repository (Tulips-R) has started assigning DOI to all doctoral dissertations accepted as doctoral degree requirements in the university.


For more information about DOI, please refer to https://tsukuba.repo.nii.ac.jp/?page_id=24.


To those who completed their doctoral degrees before April 2017 and would like to have DOIs assigned to their doctoral dissertations, please contact  tulips-r#@#tulips.tsukuba.ac.jp (「#@#」→「@」)


※ Please note that the National Diet Library already assigned DOI names to doctoral dissertations submitted from 1991 to 2000 with authors' permission for open access to the doctoral dissertation's digital information.
