This is a thorough investigation of the material and philosophical aspects of conserving contemporary art. Since the advent of the avant-garde in the early 20th century, visual artists have adopted new techniques and materials, some of whose characteristics of aging and wear are still largely unknown today. The conservator's intervention has become increasingly delicate, problematic, and experimental and requires not only technical knowledge of these materials but also a greater awareness of the artist's intellectual universe. "Conserving Contemporary Art" is one of the first books to give a comprehensive overview of the many considerations faced by the conservator of modern and contemporary art.
