The IHR library holds copies of most University of London PhD (and some MA) theses in history, from the early twentieth century to 2009. Since 2009 University of London theses are now only held by the relevant college library. The pre-2009 copies formerly held by Senate House Library were offered back to the college libraries, and the IHR still holds most of the second copies. The copies can be requested from the IHR's onsite store, and are included on the IHR catalogue.
Recent copies of IHR students' theses can be accessed on the School of Advanced Study repository.
We don't loan or copy theses, and most UK PhD theses are now only available through the British Library’s EThOS (Electronic Theses Online) service. These can usually be digitised on demand if they are not already available, and some universities subsidise the costs. A list of participating institutions is available at http://ethos.bl.uk/HEIList.do. Oxford and Cambridge aren't participating, so enquiries for their theses should be made directly to the institutions. MPhil/MA theses are not covered by EThOS, so enquiries should be made directly to the relevant university. University of London MPhil/MA and non-college PhD theses may be available on inter-library loan or document supply from Senate House Library.
The IHR publishes a list of history theses annually in print format and online on History Online. We do not hold copies of these theses, except where they fall into the collection described above. Enquiries for accessing copies can be made via EThOS or the relevant institution.
