Ethical Sampling Guidance

Resource

When sampling decisions for scientific investigations of heritage objects or sites are collaborative and transparent between researchers and owners/custodians, they encourage balanced, objective and consistent discussions and conclusions. However, finding, sharing or communicating information to support and direct common-ground decisions from multi-perspectives is not always easy. To fill this important information gap, the Heritage Science Group committee of the Institute for Conservation (Icon) has developed this guidance for materials research.
