Bestandserhaltung als Risikosteuerung.

Preservation consists in avoiding or changing, as far as possible, any materials, techniques and behaviour patterns that have been identified as risk or danger to cultural heritage. Today, preservation deals with large quantities and masses. The infrastructure and the damage survey system established at the Duchess Anna Amalia Library in Weimar after the fire in 2004 serve to illustrate some aspects of the risk management.
