The Abbey Library of Saint Gall has one of the most important collections of manuscripts in Switzerland.
The library holds numerous documents including incunabula, early prints, large collections dating from the 2nd half of 18th Century, as well as manuscripts of the late Humanism and Confessionalism periods.
The virtual library Codices Electronici Sangallenses (CESG) provides access to several hundred medieval manuscripts of the Abbey Library of Saint Gall.
In addition, the Abbey Library of Saint Gall also collects literature on the history of the Abbey of Saint Gall, the history of the monastery, the history of the Benedictine Order in particular, and on other specific topics.
The collections can be searched in the St.Galler Bibliotheksnetz. The catalogue of manuscripts (1875) and the catalogue of incunabula (1880) are both available online.
