museums and a tech-savvy public will find the wiki format familiar and attractive. It may soon become easier to gain meaningful contributions from older generations as well, especially as Web 2.0 software becomes increasingly user-friendly. Currently, wikis are used by museum professionals to connect multiple institutions or facilitate interdepartmental projects.1 However, there is an emerging trend in building wikis to invite community- contributed heritage content.2 For example, Now & Then,3 an Australian heritage wiki produced by the Mallala Museum, was recently launched in September 2009. Now & Then invites community members to submit photos and stories of objects they view as important to Mallala's community heritage. Using wikis for museum collaboration is a strategy consistent with the changing role of the museum in society, and leads to improved cultural understanding. It is also important to consider the institutional implications for museums that embrace participatory projects and the wiki's intersection with the museum's changing role. These issues that my project raises are currently gaining momentum in the museum field today. The Fall 2009 issue of the AAM exhibits journal, The Exhibitionist, focuses its content entirely on "Visitor-Generated Content and Design."
