Depending on the origin of the dissertation different databases are suitable for searching. If you can't find or access the thesis you are after online nor is it available for loan via NEBIS, don't hesitate to contact us. We are happy to be of help. Please note that access to some of the following databases is even quicker using the Lib4RI-Searchbox (select «More», then click «Dissertations»).

swissbib (Swiss theses) OPEN DATABASE 

Swissbib is the metacatalogue of more than 800 Swiss libraries (incl. the NEBIS network). It provides a simple, fast and comprehensive gateway to scientifc information. Generally, swissbib is the best entry point for tracking down Swiss dissertations. Obtained search results indicate library holdings, and particularly for more recent theses include links to the fulltext (e.g. to ETH's e-collection).

Please use Swissbib's Advanced Search to limit the format for your search to «Buch(Hochschulschrift)».
