These are useful sources for theses.
Run by the British Library, this is a service providing access to theses held at higher education institutions throughout the UK. Where electronic access is not currently available it is possible to request digitisation of a thesis, however, there is a charge for this service.
Since September 2009 electronic copies of all University of Dundee research theses have been deposited in Discovery, the University's repository. There are also copies of theses awarded before 2009 that have been deposited by University staff.
