Museums need to find answers to what it means to be part of a participative culture, a culture in which members believe that their contributions matter and feel some degree of social connection with one another. In documenting contemporary culture, participative projects add new perspectives to collections. At the same time they provide participants with a better understanding of the specificity of museum work. This better understanding fosters people’s sense of ownership in a museum. Yet, the participative method of collecting is not uncontested. It may question the autonomy and authority of the museum professional, involving a redefinition of the professional as an external expert acknowledging the expert knowledge of the individual and the community itself.
