Following Wiedemann's design, the famous library was built in the North wing of the abbey. At the time of completion in 1744, the works were already supervised by Christian Wiedemann's nephew Johann Wiedemann. In 1750, a new superintendent, Johann Michael Fischer, was appointed. He revised the original plans by Wiedemann. His main achievement is the new design for the East wing which was given a conspicuous risalit thereby emphasizing on the one hand the role of the chapter house as the centre of the monastic organisation and the fact that it was also the centre of a semi-sovereign territorial unit of power. The facade of this building was modelled on the Imperial Court Library in Vienna which was chosen in order to demonstrate the abbey's attachment to the imperial house.
