E-Theses Online Service (EThOS) was a bibliographic database and union catalogue of electronic theses provided by the British Library, the National Library of the United Kingdom. As of February 2022 EThOS provided access to over 500,000 doctoral theses awarded by over 140 UK higher education institutions, with around 3,000 new thesis records added every month until the British Library cyberattack forced the service to be temporarily taken offline.

Data recorded in EThOS

Theses 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.

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, EThOS has integrated authority control and other unique identifiers including:

• The author's ORCID identifier..
• The International Standard Name Identifier (ISNI).
• The Handle System.
• Digital Object Identifiers (DOIs).

Some thesis records include the name of the doctoral advisor.

Doctoral advisor metadata can be used in academic genealogies like academictree.org, Wikidata and the Mathematics Genealogy Project. Academic genealogies in Wikidata are built using the doctoral advisor relation (Property:P184).

Searching EThOS metadata

Where present, metadata can be used as search criteria. So for example, in addition to a basic search, 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. Data in EThOS can also be accessed programmatically (by machines) using the Protocol for Metadata Harvesting (PMH) from the Open Archives Initiative (OAI), DataCite and its Application Programming Interface (API).

Types of thesis included

As well as indexing Doctor of Philosophy theses, EThOS holds records of other kinds of doctorates including:

• Doctor of Medicine (MD) theses, for example Pensée Wu's thesis.
• Doctor of Science (ScD or DSc) theses, for example Else Bartels thesis.
• Doctor of Engineering (EngD or DEng) theses, for example Chris Dighton's thesis.
• Doctor of Professional Studies (ProfD or DProf) theses, for example Andreas Georgiou's thesis.
• Doctor of Music (MusD or DMus) and Doctor of Musical Arts (DMA) theses, for example Evaristo Lopez thesis.
• Doctor of Education (EdD or DEd) theses, for example Mary Greaves thesis.
• Doctor of Philosophy (PhD or DPhil) by prior publication in peer reviewed journals, for example Jill Steward's thesis.
• Doctor of Philosophy in creative writing, for example Sally O'Reilly's thesis.

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 contact

EThOS 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. EThOS staff at the British Library can be contacted during office hours on email, Twitter and in person at the British Library.

Availability

EThOS was taken offline by the British Library cyberattack and has been unavailable since December 2023.
