To highlight the specific changes produced by social media, the book is structured around three major themes: provides readers with a critical framework to understand how the participatory culture fostered by social media changes the way in which we experience and think of heritage. By introducing readers to how social media are theorized and used, particularly outside the institutional domain, the volume reveals through groundbreaking case studies the emerging heritage practices unique to social media. In doing so, the book unveils the new issues that are emerging from these practices and the new space for debate and critical argumentation that is required to illuminate what can be done in this burgeoning sector of heritage work.
