In 1880, the Catholic Administration (Katholische Konfessionsteil) of the Canton of St. Gall commissioned Gustav Scherrer (1816-1892), a scholar and professor from St. Gall, to draw up the first printed catalogue of the incunabula kept at the Abbey Library of St. Gall (PDF document of the title page). This volume contains descriptions of the St. Gall incunabula, which at that time numbered 1558. The catalogue also includes several detailed registers and appendices. There is still no modern replacement for Scherrer's work, which was considered exemplary at the time. An unprinted typescript contains descriptions of the incunabula numbered from 1559 until 1651, which are added later to the collection.
This catalogue of incunabula has been available in electronic form since May 2009.
