That's a phrase that I just learned today, although it was coined many decades ago (just “wikipedia” it to find out more about its history).
If citizen science allows people with no formal scientific training for that particular project to participate effectively, e.g. conducting bird counts in some remote site (notice that a physicist is a scientist but she’s not trained as an ornitologist), how can we do the same for heritage conservation? That is, how do we involve “ordinary folks” to be interested and thus participate in heritage project?
citizen heritage, anyone?
