EThOS is the UK’s national thesis service which aims to maximise the visibility and availability of the UK’s doctoral research theses. It demonstrates the quality of UK research, and supports the UK Government’s open access principle that publications resulting from publicly-funded research should be made freely available for all researchers, providing opportunities for further research. EThOS helps institutions to meet the expectation of the UK Research Councils that PhDs supported by a Research Council Training Grant should be made freely available in an open access repository, as indicated in its Training Grant Terms & Conditions (Paragraph 104).
