ORCA at Cardiff University
ORCA is Cardiff University's own institutional repository. From August 2011, an electronic copy of all research degree theses by Cardiff University students has been deposited in ORCA. Some copies of older theses have also been added to ORCA.
ORCA's Advanced Search screen gives you the option to include only theses in your results list and to narrow your search by Subject or School.
Printed copies of research degree theses submitted by Cardiff University students prior to August 2011 can be found in our Libraries. You can use our Library Catalogue, LibrarySearch, to search for these theses. Add the term ‘thesis’ along with your keywords in the search box to bring back the most relevant results.
