You can search for theses in several ways. One method is to go to the catalogue at:http://blacklight.hull.ac.uk/ and choose the option Title from the drop down menu. Type in: University of Hull Thesis. Then limit your search by the categories on the left. Alternatively, on the catalogue page, select Format from the Browse section underneath the search box. Choose the Thesis option (can choose A-Z sort). From there you may select by relevance by using tabs on the left of the screen.
