Many libraries will not lend dissertations or theses, but some will. Virginia Polytechnic Institute & State University has posted a handy Dissertation/Thesis YES/NO list.

The Center for Research Libraries has a large collection
of foreign dissertations. These are not yet cataloged in
the CRL catalog, so check the list provided for further information.
If you are not a CRL member library there is a substantial charge to borrow,
but there may be times when it will be worth the cost. CRL
also has a microfilm set: University of Cincinnati dissertations, Programmschriften,
and pamphlets in classical studies. (Assured Micro-Service) (#18500827)
309 reels.
This is a set of dissertations and other materials on classical studies,
written in German, Latin and French. The set is cataloged, and individual
titles are analyzed in the Center's catalog.
