This book investigates the selection process of heritagisation to understand what specific pasts are being selected or rejected for representation, who is selecting them, how and to whom they are being represented and why they are being presented, or dismissed, in the ways that they are. It also deals with products (e.g. tobacco), historical periods (e.g. the Third Reich), and scientific techniques (e.g. genetic modification) with negative connotations that extend beyond their heritage attributes.
