Whether or not museums can live up to the ideal that they provide a public forum has become something of a moot point, if not a stereotype of the past three decades. Museum studies researchers, scholars, and professionals have been proactive in their attempts to understand whether museums can or do provide a physical manifestation of what has been generally considered an aspirational concept or model of practice. Some have been directly inspired by philosophers and sociologists such as Jürgen Habermas (1991), Nancy Fraser (1990), and Craig Calhoun (1992), as well as the critical cultural studies “movements” that have circulated around interdisciplinary journals such as Theory, Culture and Society (http://tcs.sagepub.com/) and Public Culture (http://www.publicculture.org/). Others have drawn on current and emerging directions in disciplines such as anthropology, history, and geography to explore the public sphere concept from the perspective of transnational and postcolonial concerns, and have been influenced by theorists including Seyla Benhabib (1992), Arjun Appadurai (1996), Dipesh Chakrabarty (2000), and Aihwa Ong (2006). Ultimately, of course, much of the museum-focused work—within which we include both the theoretical and the applied (for example, exhibition-based)—has been interdisciplinary. Like the wider critical debates on which it draws and to which it contributes, museum scholarship has been aff ected by ongoing global change, and has reflected—and, in many national contexts, influenced—public policy shifts before and since the new millennium.
