The Library has a full set of Imperial PhD theses.

The majority of Imperial PhD theses are available on open access, while some are restricted to 'Imperial users only', in the Spiral repository.

We also provide access, to Imperial students and staff, to some Imperial Master's dissertations and online theses from other universities in the UK and worldwide.
