The 14th-century Registrum of Goswin in the archives contains the oldest description of the history of Marienberg: the Urbar (rent-roll) of Goswin gives an insight into the history of its earliest economic workings.
The “GOSWIN” Foundation of the abbey library and the Marienberg archives takes its name from Prior Goswin (d. ca. 1393), librarian, historian and chronicler of Marienberg. Their purpose was to support the new building works and the restoration and promotion of the abbey library and the Marienberg archives. The association was dissolved after the opening of the liberary in spring 2019.
