EThOS: e-theses online service Open access EThOS: e-theses online service Open access

EThOS, provided by the British Library, is a free online service providing access to UK doctoral theses.

Access EThOS is an open access resource.

Content  EThOS, provided by the British Library, is a free online service providing access to UK doctoral theses. It does not cover MPhils or master's dissertations.

EThOS aims to provide a central listing of all doctoral theses awarded by UK higher education institutions, with the full text of as many theses as possible. 

The database includes more than 600,000 records. Around 4,000 law theses are covered, dating from the 1920s to the present day.

Searching  EThOS has basic and advanced search facilities. Searches can be limited to theses available for immediate download.

Advanced search allows users to search by author, title, awarding body, year of award and other criteria. Boolean connectors (AND, OR, AND NOT) can be selected from a drop-down menu

Downloading  Many theses are available for download; it is necessary to create a free account to do this. 

There is an option to request digitisation of a thesis if it is not yet available for download. Sometimes this is free, but sometimes there is a charge (see FAQs). 

Help A Help menu and an FAQ page are available.

Physical & Digital Collections

Theses & dissertations: home, access to theses and dissertations from other institutions and from the university of cambridge.

This guide provides information on searching for theses of Cambridge PhDs and for theses of UK universities and universities abroad. 

For information and guidance on depositing your thesis as a cambridge phd, visit the cambridge office of scholarly communication pages on theses here ., this guide gives essential information on how to obtain theses using the british library's ethos service. .

On the last weekend of October, the British Library became the victim of a major cyber-attack. Essential digital services including the BL catalogue, website and online learning resources went dark, with research services like the EThOS collection of more than 600,000 doctoral theses suddenly unavailable. The BL state that they anticipate restoring more services in the next few weeks, but disruption to certain services is now expected to persist for several months. For the latest news on the attack and information on the restoration of services, please follow the BL blog here:  Knowledge Matters blog  and access the LibGuide page here:  British Library Outage Update - Electronic Legal Deposit - LibGuides at University of Cambridge Subject Libraries

A full list of resources for searching theses online is provided by the Cambridge A-Z, available here .

University of Cambridge theses

Finding a cambridge phd thesis online via the institutional repository.

The University's institutional repository, Apollo , holds full-text digital versions of over 11,000 Cambridge PhD theses and is a rapidly growing collection deposited by Cambridge Ph.D. graduates. Theses in Apollo can be browsed via this link . More information on how to access theses by University of Cambridge students can be found on the access to Cambridge theses webpage.   The requirement for impending PhD graduates to deposit a digital version in order to graduate means the repository will be increasing at a rate of approximately 1,000 per year from this source.   About 200 theses are added annually through requests to make theses Open Access or via requests to digitize a thesis in printed format.

Locating and obtaining a copy of a Cambridge PhD thesis (not yet available via the repository)

Theses can be searched in iDiscover .  Guidance on searching for theses in iDiscover can be found here .   Requests for consultation of printed theses, not available online, should be made at the Manuscripts Reading Room (Email:  [email protected] Telephone: +44 (0)1223 333143).   Further information on the University Library's theses, dissertations and prize essays collections can be consulted at this link .

Researchers can order a copy of an unpublished thesis which was deposited in print form either through the Library’s  Digital Content Unit via the image request form , or, if the thesis has been digitised, it may be available in the Apollo repository. Copies of theses may be provided to researchers in accordance with the  law  and in a manner that is common across UK libraries.  The law allows us to provide whole copies of unpublished theses to individuals as long as they sign a declaration saying that it is for non-commercial research or private study.

How to make your thesis available online through Cambridge's institutional repository

Are you a Cambridge alumni and wish to make your Ph.D. thesis available online? You can do this by depositing it in Apollo the University's institutional repository. Click here for further information on how to proceed.    Current Ph.D students at the University of Cambridge can find further information about the requirements to deposit theses on the Office of Scholarly Communication theses webpages.

UK Theses and Dissertations

Electronic copies of Ph.D. theses submitted at over 100 UK universities are obtainable from EThOS , a service set up to provide access to all theses from participating institutions. It achieves this by harvesting e-theses from Institutional Repositories and by digitising print theses as they are ordered by researchers using the system. Over 250,000 theses are already available in this way. Please note that it does not supply theses submitted at the universities of Cambridge or Oxford although they are listed on EThOS.

Registration with EThOS is not required to search for a thesis but is necessary to download or order one unless it is stored in the university repository rather than the British Library (in which case a link to the repository will be displayed). Many theses are available without charge on an Open Access basis but in all other cases, if you are requesting a thesis that has not yet been digitised you will be asked to meet the cost. Once a thesis has been digitised it is available for free download thereafter.

When you order a thesis it will either be immediately available for download or writing to hard copy or it will need to be digitised. If you order a thesis for digitisation, the system will manage the process and you will be informed when the thesis is available for download/preparation to hard copy.

See the Search results section of the  help page for full information on interpreting search results in EThOS.

EThOS is managed by the British Library and can be found at http://ethos.bl.uk . For more information see About EThOS .

World-wide (incl. UK) theses and dissertations

Electronic versions of non-UK theses may be available from the institution at which they were submitted, sometimes on an open access basis from the institutional repository. A good starting point for discovering freely available electronic theses and dissertations beyond the UK is the Networked Digital Library of Theses and Dissertations (NDLTD) , which facilitates searching across institutions. Information can also usually be found on the library web pages of the relevant institution.

The DART Europe etheses portal lists several thousand full-text theses from a group of European universities.

The University Library subscribes to the ProQuest Dissertations and Theses  (PQDT) database which from August 31 2023 is accessed on the Web of Science platform.  To search this index select it from the Web of Science "Search in" drop-down list of databases (available on the Documents tab on WoS home page)

PQDT includes 2.4 million dissertation and theses citations, representing 700 leading academic institutions worldwide from 1861 to the present day. The database offers full text for most of the dissertations added since 1997 and strong retrospective full text coverage for older graduate works. Each dissertation published since July 1980 includes a 350-word abstract written by the author. Master's theses published since 1988 include 150-word abstracts.

IMPORTANT NOTE: The University Library only subscribes to the abstracting & indexing version of the ProQuest Dissertations and Theses database and NOT the full text version.  A fee is payable for ordering a dissertation from this source.   To obtain the full text of a dissertation as a downloadable PDF you can submit your request via the University Library Inter-Library Loans department (see contact details below). NB this service is only available to full and current members of the University of Cambridge.

Alternatively you can pay yourself for the dissertation PDF on the PQDT platform. Link from Web of Science record display of any thesis to PQDT by clicking on "View Details on ProQuest".  On the "Preview" page you will see an option "Order a copy" top right.  This will allow you to order your own copy from ProQuest directly.

Dissertations and theses submitted at non-UK universities may also be requested on Inter-Library Loan through the Inter-Library Loans department (01223 333039 or 333080, [email protected] )

The Electronic Theses Online System

The Electronic Theses Online System is a service from the British Library that provides online access to the full-text of UK doctoral theses. It contains over 380,000+ records of doctoral theses from UK Higher Education Institutions. Many of these have already been digitised and are available for immediate download.

Can I request UK theses from other universities from the Library?

You no longer request theses from other universities through Sussex University's Interlibrary Requests service - you can access them directly via EThOS.

Do I need to register?

You do not need to register to search the 380,000+ records in the EThOS database, but you will need to register if you would like to download a thesis.

Are immediate downloads available?

If the thesis in which you are interested has already been digitised, you will be able to download it immediately without charge. If the thesis you need has not yet been digitised, there will be a short delay whilst digitisation takes place. You will then be notified by EThOS when the thesis is ready to be downloaded. Once the thesis has been digitised it is then available for immediate download by any other user.

Are all theses digitised?

Some theses cannot be digitised for copyright reasons. If this is the case with the thesis you need, please inform the Interlibrary Requests team who will investigate whether a hard copy can be borrowed directly from the relevant university.

Does this service cost me anything?

On rare occasions you may be asked by EThOS to pay for the digitisation of a thesis. This is because, although the majority of institutions participating in EThOS have agreed to pay for the digitisation of their own theses on request, some institutions have not.

In such cases, the Library will pay the cost of digitisation provided that funding is available. Please contact the Research Support team on Tel: 01273 877941 (int 7941) or Email: [email protected] with the full details of your request.

Content, coverage & description.

EThOS is a UK wide repository of digitized doctoral theses. It provides full text access to 250,000 theses published in the UK as well as bibliographic records of non digitized theses. A quick and free  registration is required to access the full text content.  

• EThOS e-Theses Online Service This link opens in a new window The British Library digital repository for UK research theses offering a central access point to UK doctoral theses. The majority of universities in the UK are members. You can cross-search over 500,000 theses including those available for immediate download. more... less... Not Searchable via One Search. You must first register on an individual basis with Ethos in order to make requests through the Ethos website. The Ethos site provides further information.

When to use

EThOS is an excellent resource for finding highly specialised and original research. S tudents embarking on a doctoral programme may wish to see examples of successful theses in their own discipline and identify areas of research that have not already been covered.  

Video guide: Using Ethos to find UK theses

University of Kent (2019) Using Ethos to find UK theses.  28 August. Available at: https://www.youtube.com/watch?v=n_c3ZRC5tG0 (Accessed: 13 July 2021).

Basic search

Keep search terms simple, e.g. 'organisational culture', 'business ethics' , ' eosinophilic inflammation', ' diabetes management'. 

Full text availability is indicated by a green open padlock symbol next to the search results.  You can restrict the search results to full text only by checking the box  ' limit search to items available for immediate download' below the search bar.

Search results are listed in order of relevance. You can change the order of results to A to Z by author or year (most recent to oldest and vice versa) by using the 'sort by" option above the search results. 

Click the relevant search result to view the abstract and download the thesis (if applicable). The full text can be accessed via the 'Immediate download'   link when this is available. You will be prompted for the username and password you chose when you registered with EThOS. 

Advanced Search

The advanced search tool enables you to search for a specific thesis by author and title. Use  the drop-down menus next to the search boxes to select your desired search criteria. 

You can also combine search terms using the Boolean operators 'AND', 'OR', 'NOT' (drop-down menu to the left of the search boxes). Example:

'higher education' (box one) AND  'social inequality' (box two)  will instruct  the database to look for theses which contain both search terms in the thesis abstracts or titles. 

'social inequality' (box one) OR  'poverty' (box two) will instruct the database to search for each search term separately. 

'higher education' (box one) AND  'social inequality' (box two) OR  'poverty' (box three) will instruct the database to search for articles which contain the first search term 'higher education' and either the second 'social inequality' or the third 'poverty'. 

Try to keep your search terms simple especially when combining search terms.  EThOS is a highly specialised database and over complicating searches may lead to a zero result outcome.

Library staff are available to help you to use all of our online databases and electronic journal services.

British Library: EThOS (Electronic Theses Online Services)

EThOS is the UK’s national open access thesis service which aims to maximise the visibility and availability of the UK’s doctoral research theses. There are approximately 350,000 records relating to theses awarded by over 120 institutions. Around 120,000 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.

Library Electronic Theses Online Service (EThOS)

The British Library provides digitised UK PhD theses online via the Electronic Theses Online Service (EThOS) .

You can search the site without registering. However, to download a thesis you must register and agree to the terms and conditions of access.

Access to theses which have already been digitised is free. If a thesis has not already been digitised, you may be asked to pay the cost of digitisation (£60) or it may be free. This depends on the policy of the institution supplying the thesis.

The EThOS database holds details of over 400,000 theses. Some of these are available for immediate download. Once you register you can download a thesis or request a digital copy if it is not currently available. If the thesis is not immediately available there will be a short delay while it is digitised.

Theses are supplied by participating institutions free of charge as zipped PDFs. Alternative formats (CD/DVD or paper) are available for an extra charge.

Participating institutions

Some institutions may not be participating in EThOS or may charge for the digitisation of a thesis. If you cannot find the theses you want or do not want to pay for the digitisation of the thesis you can still submit an Inter-Library request . However, some libraries do not lend their theses.

We will not make a request for a thesis already available on EThOS.

International & Masters Theses

You can submit an Inter-Library request for international and Masters theses.

University of London theses

The Library holds a copy of most research degree theses completed by students registered at UCL and awarded by the UoL, including many from students at Schools and Institutes prior to merger with UCL. Theses are listed by author on the Library catalogue, Explore : they are shelved in our off-campus Store and may be retrieved for consultation (24-hour notice required) by completing the store request form or via the request link on Explore. Theses are not available for loan, either to individuals or via interlibrary loan.

Some UoL research degree theses submitted by UCL students in the areas of classical, Germanic, Latin American studies; history and law are not held: check the UoL School of Advanced Study catalogue for availability.

UCL started to award its own degrees to students registering from 2007/2008. Print copies of research theses are catalogued by author in Explore and shelved in Store; electronic versions are in many cases available on open access in UCL Discovery .

If you wish to access a thesis recorded in UCL Discovery for which the full text is subject to an access restriction or not present, it is best to contact the author directly to request a copy privately.  If this is not possible, please contact the UCL Open Access Team .

If a thesis is not available via UCL Discovery or EThOS (see below) then it might be possible to obtain a copy from our interlibrary loan service via your home university interlibrary loan department. Please contact your university library and ask them to enquire about this service with UCL's Interlibrary Loan service; e-mail [email protected] for more information.

The Library does not normally hold print copies of any theses in the following categories:

• MA, MSc, MRes, LLM theses.
• Diploma theses.
• Undergraduate dissertations.
• Theses submitted at other universities or colleges.

Further information is available in the Support for dissertations and research projects LibGuide .

A growing number of open access thesis repositories is becoming available including:

• ProQuest , holds many full text theses. You can search for dissertations and theses there.
• UCL Discovery , UCL's open access research repository, includes theses alongside other UCL publications. You can search for theses, or browse a list.
• EThOS , a database run by the British Library that aims to record all UK doctoral theses, with links to access an electronic version of the full text where available. The digitisation of theses that only exist in print form can often be requested, depending on the awarding institution and for a fee: UCL supports this process for UCL-held theses.
• The DART-Europe E-theses Portal , holds details of open access electronic theses stored in repositories across Europe.
• Networked Digital Library of Theses and Dissertations , includes links to a number of international search tools and portals.

Indexes of completed theses (access available to members of UCL only)

Proquest dissertations & theses global (pqdt global).

PQDT Global contains over a million full-text dissertations and theses from 1861 onwards that are available for download in PDF format. The collection includes PQDT UK and Ireland content.

Many UK universities now decline to lend research theses. You may visit the awarding university or, increasingly, obtain an electronic version either from the university itself or from EThOS (see above).

Theses awarded by universities worldwide may be requested via UCL Library Services Interlending and Document Supply service . The normal charge for this service applies. Please note that theses are never available for loan: they must be consulted on Library premises only.

Open access for theses: how to deposit

Candidates for UCL research degrees are required to deposit an electronic copy of their final thesis in UCL's Research Publications Service (RPS), to be made open access in UCL's institutional repository, UCL Discovery . Theses are amongst the most highly-downloaded items in UCL Discovery . Making your thesis open access will mean that it is accessible worldwide, to anyone who wants to read it.

It is also possible, but not mandatory, to submit a print copy of your thesis to the Library for storage and preservation if you wish. We recommend submitting the print copy in cases where the electronic copy cannot be made openly available online in UCL Discovery, but you wish the print copy to be accessible to members of the Library.

Please refer to our guidance on how to deposit  for further information on the submission procedures.

Finding UK theses

The Bodleian Libraries hold copies of some UK theses. These are listed on SOLO  and may be ordered for delivery to a reading room. 

These theses are not all catalogued in a uniform way. Adding the word 'thesis' as a keyword in SOLO may help, but this is unlikely to find all theses, and may find published works based upon theses as well as unpublished theses.

Card catalogue  

Some early theses accepted for higher degrees and published before 1973 are held in the Bodleian Libraries but are not yet catalogued on SOLO. These holdings can be found in the Foreign Dissertations Catalogue card index.

To request access to material in the catalogue, speak to library staff at the Main Enquiry Desk in the Lower Reading Room of the Old Bodleian Library, or contact us via  [email protected]  or phone (01865 277162). 

Other finding aids

Proquest dissertations & theses.

You can use ProQuest Dissertations & Theses Global  to locate theses accepted for higher degrees at universities in the UK and Ireland since 1716. The service also provides abstracts of these theses.

Library Hub Discover

You can use Library Hub Discover to search the online catalogues of some of the UK’s largest university research libraries to see if a thesis is held by another UK library.

EThOS is the UK’s national thesis service, managed by the British Library. It aims to provide a national aggregated record of all doctoral theses awarded by UK higher education institutions, with free access to the full text of many theses. It has around 500,000 records for theses awarded by over 120 institutions.

UTREES - University Theses in Russian, Soviet, and East European Studies 1907–

UTREES is a bibliographical database of research in the British Isles. The database has been continuously extended from the printed volume, most recently with 202 recent theses added in 2021. The database lists details of over 6,000 doctoral and selected masters’ theses from British and Irish universities. It covers research relating to Eastern and Central Europe, Russia and the area of the former USSR, including Central Asia, the Caucasus and Siberia.

Individual universities

You can also go to individual UK universities' sites for their online theses repositories.

You can purchase copies of Cambridge University theses through the Cambridge University Library's online order form . There is a standard charge of £75 (plus VAT and postage). White Rose ETheses Online is an online repository of doctoral theses from the Universities of Leeds, Sheffield and York. It is part of a national and international network of open access online databases which promote access to research outputs. Many theses have been digitised by the British Library as part of the EThOS. However, there have been instances where theses are available via WhiteRose eTheses Online before they reach EThOS.  

Ordering UK theses

Many theses from other UK universities are available from the British Library's EThOS service.  Unfortunately, this service is currently unavailable due to a cyber attack on the British Library.  

You can also request theses from other UK universities as an inter-library request .

Please note that it may not be possible to obtain some theses due to restrictions on lending placed by the author of the thesis or the institution at which it is held.

DISCOVER and the Library Catalogue have been replaced by Library Search . We're busy updating all of our links, but in the meantime, please use Library Search when searching for resources or managing your Library Account.

The EThOS service is currently unavailable a result of a cyber-attack . Updates on British Library services are available via their blog .

Whilst the British Library is working to restore access to EThOS their online catalogue now provides access to digital doctoral theses held in UK institutional repositories - Using Advanced search and selecting 'Theses' from 'Material Type' dropdown menu  is recommended. To access these documents, search for a thesis and then click on a title of interest to view the full details for that work. The link can be found under the section labelled "View Online - External Resource Available" (in green) just above the "I want this" section (in red) at the bottom of the page.

See the following examples of finding theses that are available ( Available Online in green with a link to the thesis) and those that aren't (red box with 'This item is not currently available' text).

Available thesis

Unavailable thesis

EThOS (Electronic Theses Online Service) provides access to UK doctoral theses from The British Library, in association with higher education institutions in the UK. Most available theses are PhDs, but also other types of doctoral thesis, e.g. D.Ed., Mus.D., D.Eng (for M Phil and other theses contact our Get It For Me  service).

The EThOS service is currently unavailable. Updates on British Library services are available via their blog .

The British Library online catalogue now provides access to digital doctoral theses held in UK institutional repositories. To access these documents, search for a thesis and then click on a title of interest to view the full details for that work. The link can be found under the section labelled "View Online - External Resource Available" (in green) just above the "I want this" section (in red) at the bottom of the page.

You can search for all the UK theses currently listed in the British Library Catalogue and download any of the full-text theses that are already held in EThOS, either directly or via links to an institution’s own repository.  EThOS replaced the British Theses Service - microfilms are no longer available from the British Library.

How to use EThOS

To read or download theses:

• register for your own personal account with EThOS
• search the database yourself
• before you can download a thesis you must accept the terms and conditions of use; they protect the rights of the author or other rights owners
• if you need help, get in touch with the  Inter-Library Loans Team  or your Liaison Librarian .

If the doctoral thesis you want is held by EThOS you can download it immediately free of charge.

How to request a thesis that is not available for immediate download

If a digitised version of a thesis cannot be made available, EThOS will let you know. You can then make a request  through the  Get It For Me  service,  who will try to obtain the original copy of the thesis direct from the institution that holds it.

NOTE: Non-members of the University of Liverpool who wish to consult UoL theses and are unable to visit the Library in person should use the EThOS service to access them.

*   Mandatory field

Interlayer phenomena, revealed by high‐voltage electron microscopy (HVEM) and high‐resolution electron microscopy (HREM), are presented as they occur in various SiC(Nicalon) fibre‐reinforced Duran glass composites (differing in the specific sol‐gel supported production processes). Their dependence on the production parameters and their influence on the materials properties are discussed, taking into account the results of scanning electron microscope (SEM) in situ tensile tests.

Besides graphitic carbon, textured to a variable degree and influencing the tensile behaviour, oxycarbide formation is indicated.

A reactive matrix additive, such as, e.g. TiO 2 , resulted in a decrease in strength and a brittle behaviour, while the addition of ZrO 2 markedly improves the mechanical properties.

LONDON (AP) — Two environmental activists attacked a glass case containing an original copy of the Magna Carta at the British Library on Friday, causing minor damage to the reinforced box but leaving the historic document unscathed.

The pair of protesters from Just Stop Oil, a group that has caused widespread disruption in Britain in its campaign to end to the world’s reliance on fossil fuels, pounded on the case with a hammer and chisel.

The Rev. Sue Parfitt, 82, and Judy Bruce, 85, a retired biology teacher, released a statement saying that they targeted the document to highlight the dangers of climate change.

“The Magna Carta is rightly revered, being of great importance to our history, to our freedoms and to our laws,’' Parfitt said. ”But there will be no freedom, no lawfulness, no rights, if we allow climate breakdown to become the catastrophe that is now threatened.”

London’s Metropolitan Police said that two people were arrested.

The library’s security team intervened to prevent further damage to the case surrounding the Magna Carta, which is considered one of the founding documents of Western democracy.

The Treasures Gallery is temporarily closed until further notice, the library said.
