Conservation in the Age of Consensus [PDF ebook] 

This new text on the subject of conservation in the built environment provides a unique holistic view on the understanding of the practice of conservation connecting it with wider societal and political forces. UK practice is used as a means, along with international examples, for bringing together a real understanding of practice with a social science analysis of the issues. The author introduces ideas about the meanings and values attached to historic environments and how that translates into public policies of conservation.
