Boundary work is essential for public engagement. Establishing the actual role and power of citizens and stakeholders in, e.g. selecting research projects to be funded, identifying the research questions to be addressed or collecting research data always implies a boundary work, i.e., a negotiation process among the concerned players. Public engagement initiatives are themselves “boundary places”, where different kinds of knowledge, expectations and interpretations interact in a unique context.

However, it is difficult to exactly identify sets of practices which can specifically refer to as “boundary work”. Yet, some authors, studying cases of boundary works in different contexts, came to single out some specific boundary practices. Some examples are provided below.
