Sets of theses and dissertations produced by University of Bristol staff and students, for qualifications including PhD, BSc, BA, BEd, BDS, BVSc, LLB, MB, MDS, MPhil, MSc and ChB, are available in some of the branch libraries. For details of the thesis collection in a particular branch you should use the branch libraries option. You are likely to need to ask library staff to fetch a thesis for you to see, and theses are usually confined to the branch library.
Theses and dissertations are treated as books on the online Library Catalogue (also available on the Quick search > Books, etc option of the Library home page); therefore search for them as if you were trying to find a book, using either the author's name, the title or a combination of the two. You can restrict your search to UoB theses by using the 'Material type' UoB theses search.
To search for theses from other universities you could try using the Material type--Theses category on MetaLib (easily accessed via the Quick search > Articles & databases option of the Library home page) which gives you access to a number of thesis databases, or you could search their catalogues directly by going through lib-web-cats: an International Directory of Libraries. If you would like to see a thesis from another university you should consider using the Inter-Library Loan service.
Advice on how to submit a thesis for a higher degree can be found via the Examinations Office web pages, and in particular:
