The collection of the Bibliothek Andreas Züst was re-cataloged in 2014/15. The original, only limited classical bibliographical inventory can be searched via the filter as well as the categories (in German only) listed below. These go back to an ordering system created in 2003 by Plinio Bachmann.

The re-cataloged library collection is retrievable through the St. Galler Bibliotheksnetz SGBN. This follows the rules of the Sacherschliessung im IDS, for which the keywords of the ‘Gemeinsamen Normdatei GND/S’ have been used as a controlled vocabulary. The catalog itself is available only in German, however, the library collection includes titles of books in the original language, so that any books in, e.g., English in the collection can also be discovered.
