Cultural Heritage and Tourism Development may be strong driving factors for local policies and may have great importance in strategic decision making at territorial level; then, they may be important subjects for eParticipation studies. But this paper demonstrates, through a literature review, that today's disciplinary shape of eParticipation as a research field is not suitable to effectively investigate participatory processes related to Tourism and Cultural Heritage. Then, by presenting a field research, which took place in the Italian city of Genoa, and by confronting its outcomes with some most widespread disciplinary eParticipation underpinnings, the paper seeks to identify some areas where a widened disciplinary scope is particularly needed. Finally, we propose a new disciplinary framework, suitable to address also Cultural Heritage and Tourism Development eParticipation processes.
