Printed theses held in the Balfour Library

A collection of over 500 theses written by members of the Department of Zoology are kept in the Library Office.

These are for reference only and are catalogued in the card catalogue drawer marked "Theses" alphabetically by author’s surname, as well as online in iDiscover.

The collection is by no means complete. If you cannot find the thesis you want, please ask the Senior Library Assistant for help in locating a copy.

A copy of all the theses written by University of Cambridge students must be deposited at Cambridge University Library however, please see "Print theses held in Cambridge" below.


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. Catalogue records of theses approved from 1970 onwards can be found on iDiscover. 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 information.


Electronic Cambridge theses

From the start of Michaelmas Term 2009 it is possible to access and deposit theses in electronic form in Apollo, the University 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 at:


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 web page on Inter-Library Loans at

The British Library also has a new Electronic Theses Online Service (EThOS)


International theses, electronic and in print

Try some of the "Quick links" on the right hand side of this page to locate national and international theses, either in digital or print format. The Quicklink to the "Theses and Dissertations LibGuide" details how you can access theses held in Cambridge, the UK and international institutions.

Many universities around the world now require their Ph.D. or Masters students to provide their theses in electronic format, 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.
