EThOS is the UK’s national thesis service which aims to maximise the visibility and availability of the UK’s doctoral research theses. EThOS aims to provide a national aggregated record of all doctoral theses awarded by UK Higher Education institutions and free access to the full text of as many theses as possible for use by all researchers. There are approximately 440,000 records relating to theses awarded by over 120 institutions of which around 160,000 are available as full text. Requests for many of the remainder can be ordered for scanning through the EThOS digitisation-on-demand facility. You can download digitised PhD thesis from across the UK for free once you have registered on the website. Records are held for all UK PhD-awarding institutions, but EThOS does not yet hold all records for all institutions. This is constantly updated as more theses including University of Manchester outputs from March 2013 are submitted solely in electronic form.
