E-Theses Online Service (EThOS) is a bibliographic database and union catalogue of electronic theses provided by the British Library, the National Library of the United Kingdom.[1][2][3][4] As of July 2026 EThOS provides access to over 650,000 doctoral theses[5] awarded by over 140 UK higher education institutions,[6] with around 3,000 new thesis records added every month[7][8][9][10][11]. The service was taken offline for three years from 2023 to 2026 following the British Library cyberattack.[12] EThOS servicesEThOS records thesis data and metadata which can then be searched with basic[4] and advanced search terms.[19] Data recorded in EThOSTheses indexed by EThOS have a minimum of a thesis title, author, awarding body and date. Optional additional metadata may be included such as the thesis abstract, doctoral advisor, sponsor, cross links to other databases and the full text of the thesis itself.[19] As of September 2017 the EThOS website gives open access to the full text of around 160,000 UK doctoral theses that have been digitised. Theses can be accessed by freely registering for then logging into EThOS. Open access is also provided by links to the Institutional repository of the awarding body. Since 2015,[8] EThOS has integrated authority control and other unique identifiers including:
Some thesis records include the name of the doctoral advisor. Doctoral advisor metadata can be used in academic genealogies like academictree.org,[20][21] Wikidata[22][23] and the Mathematics Genealogy Project. Academic genealogies in Wikidata are built using the doctoral advisor relation (Property:P184).[22] Searching EThOS metadataWhere present, metadata can be used as search criteria. So for example, in addition to a basic search,[4] an advanced search facility allows users to search for theses by publication year, awarding body, author's given name, surname, thesis title, doctoral advisor and various other metadata.[19] Data in EThOS can also be accessed programmatically (by machines) using the Protocol for Metadata Harvesting (PMH) from the Open Archives Initiative (OAI),[24] DataCite[25] and its Application Programming Interface (API).[26] Types of thesis includedAs well as indexing Doctor of Philosophy theses, EThOS holds records of other kinds of doctorates including:
Master's degree theses such as Master of Philosophy (MPhil), Master of Research (MRes), Master of Science (MSc) and Master of Arts (MA) theses are not indexed by EThoS. Honorary degrees are also not included as there is usually no actual written thesis. Development and contactEThOS was developed in partnership with Higher Education Institutions (HEIs) around the UK with funding from Research Libraries UK (RLUK) and Jisc (formerly the Joint Information Systems Committee) and was launched in January 2009.[1][35] EThOS staff at the British Library can be contacted during office hours on email, Twitter[36] and in person at the British Library. AvailabilityEThOS was taken offline by the British Library cyberattack and became unavailable in December 2023.[37][38][12] By 2026, there were plans to restore downloads and on-demand digitization "later [that year]", as well as an interim platform running solely on the platform's metadata.[39] The lack of progress on restoring EThOS has been criticised by Martin Paul Eve, who said that the interim platform lacked the centralisation central to EThOS and that the British Library had not prioritised restoration.[39] As of July 2026 the service is back online.[5] References
