Science and Technology in Historic Preservation [PDF ebook] 

Technology transfer has played an increasingly important role in historic preservation during the latter half of the twentieth century, a situation attested to by the undertaking of an important congressional study in 1986 that assessed the role of federal agencies in the field. In this book leading researchers update the earlier findings and contribute state-of-the-art reviews and evaluations of technological progress in their areas of expertise.
