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 swisscovery, 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»).

swisscovery (Swiss theses) OPEN DATABASE 

Swisscovery is the new nationwide library catalogue operated by the Swiss Library Service Platform (SLSP) replacing the former NEBIS recherche catalogue and soon also swissbib, as the best entry point for tracking down Swiss dissertations.

When searching for dissertations, please tweak swisscovery's results for the «Resource Type» «Dissertations».


WorldCat is the world's largest network of library content and services. It also includes many theses and dissertations from all over the world.
