On November 4, 1966, the Arno River in Florence, Italy, flooded its banks, breaching the basements and first floors of museums, libraries, and private residences and burying centuries of books, manuscripts, and works of art in muck and muddy water. Flood in Florence, 1966documents a symposium held to mark the 50th anniversary of a natural disaster that served as an impetus for the modern library and museum conservation professions. The proceedings feature illustrated, first-person remembrances of the flood; papers on book conservation, the conservation of works of art, disaster preparedness and response, and the continuing needs for education and training; and a keynote that points toward a future where original artifacts and digital technologies intersect. Providing new insights on a touchstone event by three generations of preservation and conservation professionals, the proceedings deepen our understanding of major advances in conservation practice and shed light on some of the most important lessons from those advances for future generations and the digital age.
