This book describes the methods of conservation, preservation and restoration of the thousands of artefacts contained within the buildings that house the museums, which also require constant care and attention. The Vatican Museums are enormous, nearly 4 miles of passages through galleries, rooms and internal gardens. A museum system that includes many specific collection types - frescoes, sculptures, metals, textiles, ethnographic, Etruscan and Egyptian artefacts, fine and contemporary art, carriages and cars - that all require expert attention, whilst they are viewed daily by some of the 6 million visitors a year, who all breathe amongst the treasures, and spread dust throughout the buildings. The book will be of great interest and value to anyone involved in, or training to be involved in the professional management of a museum or collection.
