Theses can be found on DBS eSource. eSource is our open-access institutional repository. It contains the full-text dissertations, articles, book chapters, and conference papers from DBS staff and students.
It would be considered best practice not to cite directly from a thesis but rather you can comb through the references list at the end of the thesis to see if any of the sources used are suitable sources for your research. The reason you are advised not to cite theses directly is that theses are not peer- reviewed. Generally, the sources you use in your dissertation should be peer reviewed.
