The authenticity of art has always commanded the attention of experts, dealers, collectors, and the art-minded public-especially those who relish the Robin Hoods of art forgery who deceive rich collectors and pompous experts. This book of essays, edited by a lawyer specializing in art law and authenticity, proposes to make the question of authenticity more easily understood. The main points to be argued are (1) that the perception of form in a work of art is not unlike other types of evidence accepted in courts of law; (2) that in determining authenticity, experts must adopt a careful, organized approach; and (3) that all authentication should be based on the consensus of experts at arm's length from an object.

For more than ten years, this series has been the key basic texts for conservators throughout the world. These introductory volumes provide non-scientists with the essential theoretical background to their work.

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.

Materials in Conservation is the definitive introduction to the properties of materials used in conservation. The continual struggle of conservators to ameliorate the deterioration of objects has led to increasing use of synthetic polymers. These materials are part of the sophisticated technology that has been developed to augment and often replace traditional materials and methods. Conservators therefore have a wider range of techniques available. However, they must be able to appreciate the potentials and pitfalls of any proposed technique. The first section explains physical and chemical properties which are important in the conservation process, i.e. application, ageing, reversal. The topics covered include molecular weight, glass transition temperature, solubility and solvents, polymerisation and degradation reactions. The second section provides a detailed consideration of the individual materials, current and obsolete, used in conservation, drawing out the factors relevant to their effects on objects. The conservation uses of each material are summarised and referenced to allow further study. In five appendices, the properties of the polymers, solvents and their interactions are tabulated, with a list of suppliers and conversion table of physical units. IUPAC and SI nomenclature is used throughout the book. In this second edition, this classic text is revised and updated to include modern materials such as cyclododecane, and current ideas on adhesion, consolidation and reversibility, making Materials in Conservation the definitive source of vital information in the field. This handy reference book should be on the bench of every conservator and available wherever objects, from steam engines to dried plants, are preserved.

Conservation Skills provides an overview of the issues facing conservators of historic and artistic works. It not only describes the nature of conservation but also provides an ethical framework to which the conservation of objects can be related. Drawing on case studies of well-known objects such as the body of Lindow Man and the Statue of Liberty it addresses the following issues: * perception, judgement and learning * reasons for preserving the past * the nature and history of conservation * conservation ethics * recording, investigating, cleaning objects * stabilisation and restoration * preventive conservation * decision making and responsibilities.

Conservation of Easel Paintings, Second Edition provides a much-anticipated update to the previous edition, which has come to be known internationally as an invaluable and comprehensive text on the history, philosophy and methods of the treatment of easel paintings. Including 49 chapters written by more than 90 respected authors from around the world, this volume offers the necessary background knowledge in technical art history, artists’ materials and scientific methods of examination and documentation. Later sections of the book provide information about the varying approaches and methods for treatment and issues of preventive conservation, as well as valuable reflections on storage, shipping, and exhibition. Including exciting developments that have taken place since the last edition was published, the book also covers new techniques of examination, especially MacroXRF scanning and Reflectance Transmission Imagery. Drawing on research presented at recent professional conferences, information about innovative methods for cleaning modern and contemporary paintings and insights into modern oil paints is also included. Incorporating the latest regulations and understanding of health and safety practices and integrating theory with practice throughout, Conservation of Easel Paintings, Second Edition will continue to be an indispensable reference for practicing conservators. It will also be an essential resource for students taking conservation courses around the world.

Conservation of Books is the highly anticipated reference work on global book structures and their conservation, offering the first modern, comprehensive overview on this subject. The volume takes an international approach to its subject. Written by over 70 specialists in conservation and conservation science based in 19 countries, its 26 chapters cover traditional book structures from around the world, the materials from which they are made and how they degrade, and how to preserve and conserve them. It also examines the theoretical underpinnings of conservation: what and how to treat, and the ethical, cultural, and economic implications of treatment. Technical drawings and photographs illustrate the structures and treatments examined throughout the book. Ultimately, readers gain an in-depth understanding of the materiality of books in numerous global contexts and reflect on the practical considerations involved in their analysis and treatment. Conservation of Books is a quintessential reference work for book conservators and anyone working with books, such as collection managers, librarians, curators, dealers, collectors, historians, and related professionals. It is also an indispensable text for students to complement hands-on training in this field.

Author David Saunders, former keeper of conservation and scientific research at the British Museum, explores how to balance the conflicting goals of visibility and preservation under a variety of conditions. Beginning with the science of how light, color, and vision function and interact, he proceeds to offer detailed studies of the impact of light on a wide range of objects, including paintings, manuscripts, textiles, bone, leather, and plastics. With analyses of the effects of light on visibility and deterioration, Museum Lighting provides practical information to assist curators, conservators, and other museum professionals in making critical decisions about the display and preservation of objects in their collections.

Conservation Skills for the 21st Century provides a much-needed update to the original Conservation Skills volume, presenting an overview of current issues facing conservators of historic and artistic works. Beginning with the basics – why the past is important, as well as an overview of the nature and history of conservation – the book allows the reader to develop a holistic appreciation of the subject. As with the first edition, this volume assists with the development of judgement in conservation students and young professionals. A selection of new case studies representing issues conservators are likely to face in the 21st century illustrates the crucial considerations that must be made when proposing and executing a conservation treatment. Incorporating recent developments and use of new technologies in conservation processes, the book also covers topics such as conservation ethics; recording and documentation; investigating and cleaning objects; stabilisation and restoration; values, decision-making, and responsibilities; preventive conservation; approaches to the treatment of working and socially active objects; sustainability in conservation; and the conservator’s role as advocate. With detailed case studies and written in a clear, accessible style, Conservation Skills for the 21st Century remains essential reading for student conservators and conservation professionals around the globe working across a wide range of conservation disciplines.
