About EThOS


EThOS is the UK’s national thesis service which aims to maximise the visibility and availability of the UK’s doctoral research theses.

It 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. It demonstrates the quality of UK research, and helps attract students and research investment into UK Higher Education.

EThOS aims to provide:
  • A national aggregated record of all doctoral theses awarded by UK Higher Education institutions
  • Free access to the full text of as many theses as possible for use by all researchers to further their own research.
There are approximately 350,000 records relating to theses awarded by over 120 institutions. Almost 100,000 of these also provide access to the full text thesis, either via download from the EThOS database or via links to the institution’s own repository. Of the remaining 250,000 records dating back to at least 1800, three quarters are available to be ordered for scanning through the EThOS digitisation-on-demand facility.

Records are held for all UK PhD-awarding institutions, but we do not (yet) hold all records for all institutions. Every month around 3000 new records are added and an additional 2000 full text theses become accessible. Access routes to the full text are determined by the individual institution and may depend on:
  • Mandatory electronic deposit of newly awarded theses by its students
  • Availability of its theses in the institutional repository
  • Its level of repository development
  • Digitisation prioritisation of its print theses
The digitisation on demand facility is a unique feature of EThOS and brings new e-born theses and older print content together into a single place. Users ordering a copy through digitisation on demand may experience a turnaround time of up to 6 weeks. There may also be a charge for the scanning process (currently £43.29 +VAT). Details are provided within each record.

There is a continuous programme of improvement and enhancement of the EThOS service, both for participating institutions and for users of the service. The EThOS Toolkit provides further information about all aspects of the service.
