In this article, I share an anecdote about citizen science and use it to reflect on this rapidly growing field of scientific activity, its funding, and its governance. The paper focuses particularly on the epistemic and social challenges that accompany increasing demands for professionalization and institutionalization of the Citizen Sciences.

In the half-century that elapsed between 1830 and 1880, the city of Barcelona, while industrializing and tripling its population, saw how rich scientific collections (mainly naturalistic, archeological, and anatomical) could be created or lost, opened to the public or forgotten. The complexity and variety of the movements of these collections go beyond the narrow historiographical framework defined by a supposedly linear evolution towards greater accumulation and openness to the public. On the contrary, the examples examined in this article reveal a (...) variety of paths and vicissitudes. (shrink)
