Printed theses held in Cambridge

See the Manuscripts Department's web page on Theses for further infromation.
Electronic Cambridge theses
The University repository Apollo has recently been upgraded and is now able to accept all thesis types. For the academic year 2016/17 the University is piloting electronic thesis submission with several departments, including Chemistry. If you are submitting a thesis in the academic year 2016/17, you are requested to submit an electronic thesis to Apollo alongside the print copy you need to submit to the Student Registry.
An online form has been developed for theses to make the deposit process simple and fast. Find out more about the Digital Thesis Pilot 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. 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.
