During the 1960s, an important find of a group of Viking ships occasioned the building of a new conservation plant of large proportions. This, coupled with a dissatisfaction with previous conservation methods led to the adoption of new methods for caring for waterlogged wooden remains. The methodologies developed are described in this book. English, with Danish Resume.

The impetus for this book was the desire to systematically organize the extant literature on the conservation of cultural property made of wood, from its beginnings before the Christian Era to the year 2000. Various published reviews and monographs, including Holzkonservierung (Wood Conserva tion) published by the senior author in 1988, have appeared over the years, especially in English and in German. They have provided exemplary treat merit of individual areas or aspects of wood conservation, but a comprehen sive, up-to-date exposition of historic and current developments has been lacking. The diverse professional fields of the authors, as well as their insights into methods of conservation and restoration of wood artifacts in Europe, North America, and Asia provided a solid basis for the success of this under taking. One of the goals during the examination of the literature was that not only well-known conservators and scientists from countries that are leaders in wood conservation should be represented, but that less well-known, often not as readily accessible contributions should also be included. Only in this manner was it possible to draw a comprehensive picture of the national and international state of wood conservation. The Art and Archaeology Technical Abstracts (AATA) of the Getty Institute were very helpful in our efforts to evaluate as many publications as possible.

This is a Foreword by an archaeologist, not a conservator, but as Brad Rodgers says, “Conservation has been steadily pulled from archaeology by the forces of specialization”(p. 3),andhewantstoremedythatsituationthroughthismanual. He seesthisworkasa“calltoactionforthenon-professionalconservator,”permitting “curators, conservators, and archaeologists to identify artifacts that need prof- sional attention and, allow these professionals to stabilize most artifacts in their own laboratories with minimal intervention, using simple non-toxic procedures” (p. 5). It is the mission of Brad’s manual to “bring conservation back into arch- ology” (p. 6). The degree of success of that goal depends on the degree to which archaeologists pay attention to, and put to use, what Brad has to say, because as he says, “The conservationist/archaeologist is responsible to make preparation for an artifact’s care even before it is excavated and after its storage into the foreseeable future”. . . a tremendous responsibility” (p. 10). The manual is a combination of highly technical as well as common sense methods of conserving wood, iron and other metals, ceramics, glass and stone, organicsandcomposits—afarbetterguidetoartifactconservationthanwasava- able to me when I ?rst faced that archaeological challenge at colonial Brunswick Town, North Carolina in 1958—a challenge still being faced by archaeologists today. The stage of conservation in 1958 is in dramatic contrast to the procedures Brad describes in this manual—conservation has indeed made great progress.

Over the past twenty years there has been a significant increase in underwater activities such as scuba diving which, coupled with the adventure andromance always associated with shipwrecks, has led to rapid developments in the discovery and excavation of shipwrecked material. These shipwrecks are invaluable archaeological 'time capsules', which in themajoriety of cases have come to an equilibrium with their environment. As soon as artefacts on the wreck site are moved, this equilibrium is disturbed, and the artefacts may commence to deteriorate, sometimes in a rapid and devastating fashion. In fact excavation without having conservation facilities available is vandalism--the artefacts are much safer being left on the sea bed. Such famous shipwrecks as the Mary Rose (1545), the Wasa (1628) and the Batabia (1629) have not only brought the world's attention to these unique finds, but have also produced tremendous conservation problems. The treatment of a 30 metre waterlogged wooden hull or large cast iron cannon is still causing headaches to conservators.

This volume, the result of an International Conference on Wet Site Archaeology funded by the National Endowment for the Humanities, explores the rewards and responsibilities of recovering unique assemblages from water-saturated deposits. Characteristics common to all archaeological wet sites are identified from Newfoundland to Chile, Polynesia to Florida, and from the Late Pleistocene to the Twentieth Century. Topics include innovative excavation and preservation methods; the need for adequate funding to preserve and analyze the abundant biological and cultural remains recovered only at archaeological wet sites; expanded knowledge of past environments, subsistence, technologies, artistic expressions, skeletal structure, and pathologies; the urgency to inform developers and governmental bodies about the invisible heritage entombed in wetlands that is often destroyed before it can be investigated; a formula for establishing priorities for excavating wet sites; and how to determine when enough of a wet site has been sampled.Many famous sites and discoveries are described in this volume, including Herculaneum, Hoko River, Hontoon Island, Key Marco, Monte Verde, Ozette, Somerset Levels, Windover, bog bodies of Northern Europe, and lake dwellers of Switzerland. Professional and amateur archaeologists, as well as anyone interested in archaeology or the significance of wet site archaeology will find this book fascinating.

Clearly laid out and fully illustrated, this is the only comprehensive book on the subject at an introductory level. Perfect as a practical reference book for professional and students who work with excavated materials, and as an introduction for those training as archaeological conservators.
