The Jewish library on the first floor of the Faculty of Theology, Länggassstrasse 51, is quite comprehensive, especially on questions of ancient and medieval Judaism, but it is also a reliable contact point for later periods. Many works on Jewish Studies can be found in particular in the library of the Historical Institute. Introductory materials (including dictionaries) to the history, literature and religion of Judaism, are also offered by the Basisbibliothek Unitobler.
