Prevention is an attempt to look into the future and have a positive influence on it – therefore it is one of the most important aspects in the area of collection care, the central, current field of applied research in conservation and restoration. With sustainability damage and loss are avoided, dangers averted and research conducted. Collection care is only successful, if the theory is appropriately implemented in museum practice.

For the past 140 years, Germany has been the central power in continental europe. Twenty-five years ago a new German state came into being. How much do we really understand this new Germany, and how do its people understand themselves? Neil MacGregor argues that, uniquely for any European country, no coherent, overarching narrative of Germany's history can be constructed, for in Germany both geography and history have always been unstable. Its frontiers have constantly shifted. Königsberg, home to the greatest German philosopher, Immanuel Kant, is now Kaliningrad, Russia; Strasbourg, in whose cathedral Wolfgang von Geothe, Germany's greatest writer, discovered the distinctiveness of his country's art and history, now lies within the borders of France. For most of the five hundred years covered by this book Germany has been composed of many separate political units, each with a distinct history. And any comfortable national story Germans might have told themselves before 1914 was destroyed by the events of the following thirty years. German history may be inherently fragmented, but it contains a large number of widely shared memories, awarenesses, and experiences; examining some of these is the purpose of this book. MacGregor chooses objects and ideas, people and places that still resonate in the new Germany—porcelain from Dresden and rubble from its ruins, Bauhaus design and the German sausage, the crown of Charlemagne and the gates of Buchenwald—to show us something of its collective imagination. There has never been a book about Germany quite like it.

Anthropologists have written a great deal about the coastal adaptations and seafaring traditions of Pacific Islanders, but have had much less to say about the significance of rivers for Pacific island culture, livelihood and identity. The authors of this collection seek to fill that gap in the ethnographic record by drawing attention to the deep historical attachments of island communities to rivers, and the ways in which those attachments are changing in response to various forms of economic development and social change. In addition to making a unique contribution to Pacific island ethnography, the authors of this volume speak to a global set of issues of immense importance to a world in which water scarcity, conflict, pollution and the degradation of riparian environments afflict growing numbers of people. Several authors take a political ecology approach to their topic, but the emphasis here is less on hydro-politics than on the cultural meaning of rivers to the communities we describe. How has the cultural significance of rivers shifted as a result of colonisation, development and nation-building? How do people whose identities are fundamentally rooted in their relationship to a particular river renegotiate that relationship when the river is dammed to generate hydro-power or polluted by mining activities? How do blockages in the flow of rivers and underground springs interrupt the intergenerational transmission of local ecological knowledge and hence the ability of local communities to construct collective identities rooted in a sense of place?
