This paper discusses the significance and the value of a recycling store's openness in Ansan, Gyeonggi province, with regard to the community matters of the socially-marginalized in the area. The authors conducted participant observation in the store and individual/group interviews with more than 35 people over 8 months until the closing of the store. Ansan— where the indigenous people consist of less than 2% of the city population —is an emerging industrial planning city that lacks a rich history of community experience. In this city where multicultural discourses and “Community Building Projects” are active, the most underprivileged are those living in declining residential areas at the old town. They established communal yet regulatory relationship with one another, while the relationship was based on the actions of purchase and donation in the commercial space. This relationship became apparent during the process of the collaborative oral life history program, which took place around the closure of the store. The relationship existed even before the closure but was hard to detect in the daily life of the store. The recognition of this relationship may be a result of adding, adjusting, and coordinating each other's memories and experiences when store users shared the oral life history. Moreover, this relationship was confirmed and strengthened in the oral program. The value and significance of the store as a communal space were recognized by the collaborative oral life history processes between users and volunteers as they became shared memories and small histories of their own.
