EThOS http://ethos.bl.uk is the national database for PhD theses, managed by the British Library. It's a fantastic resource for researchers, with over 100,000 UK theses freely available to download and use for your own research, and another 200,000 available to search and scan on demand.
Sara Gould, who manages the EThOS service, will host and answer questions after the webinar on 10 December 2013, 11.00am GMT.
