One goal of local communities is to create and reinforce community identity by connecting residents to their local heritage. Technologies have enabled and facilitated the creation and consumption of digitized history content provided by official history institutions as well as individuals. Although much research has been conducted to understand technical and social aspects of digital cultural heritage, little empirical research has investigated how people perceive, experience, and interact with community content that is socially generated and tied to locations, particularly with respect to building community heritage. To address this, we developed a mobile application called Lost State College (LSC) and conducted a user study with 34 local residents. The study results indicate that meaningful historic places evoked special attention from the participants, and that those who have lived in the community longer tended to contribute more to the community heritage effort. Participants utilized social features as a way of learning local history, reflecting personal experiences and stories, and co-creating rich layers of local history information from their perspectives.
