Printed theses held in Cambridge
Copies of all postgraduate theses written by students at the University of Cambridge must be deposited in Cambridge University Library. Their online Theses catalogue contains records of theses approved from 1970 onwards. For pre-1970 theses there is a card catalogue in the Manuscripts Reading Room. See the Manuscripts Department's web page on Theses for further infromation.
Electronic Cambridge theses
From the start of Michaelmas Term 2009 it is possible to access and deposit theses in electronic form in the institutional repository. There are currently two ways of doing this, either as part of the submission process for a new thesis, or if your thesis has already been examined, you can deposit it retrospectively. Further information about the scheme is available here.
UK theses, electronic and in print
You may need to consult a thesis published by another university in the UK. For information on how to access these via the University Library, see their Inter-Library Loans website.
The British Library also has a new Electronic Theses Online Service (EThOS).
International theses, electronic and in print
Try some of the "Related links" on the right hand side of this page to locate national and international theses, either in digital or print format. The Related link to the University Library's Electronic Resources page for "Databases, full text archives and other resources covering Theses" details sources of theses that Cambridge University has subscribed to. They may require a Raven password off-campus, see the table provided for more information.
Many universities around the world now require their Ph.D. or Masters students to provide their theses in electronic format, and to deposit them on their institutional repositories so that they can subsequently be downloaded by everyone for free. Try finding the website for the university that published the thesis that you are interested in and then search for "theses" or "Electronic Theses and Dissertations" or "ETDs" - or try a Google search using the same search terms and the name of the university.
ProQuest Dissertations and Theses A&I is a comprehensive collection of dissertations and theses from around the world, dating back to 1743. Access for members of the University of Cambridge is to the abstracts only but it is a good source for finding out the bibliographic details of theses.
