EThOS is the Electronic Theses Online Service, a British Library initiative which provides access to UK doctoral theses online. Many UK theses are now online via the EThOS service. It allows you to:
British university theses must be requested via EThOS. Anyone who wishes to view a UK thesis must first register for the service. If the thesis is already digitised, you will be able to download it.
If a thesis has not been digitised, you can request for a digital copy to be added to EThOS. Please note that in most cases there is a charge for this, generally around £50.
