From @maperalta, in the Spanish thread:
Yes, we would benefit from it [comprehensive directory of all natural history collections], mostly given the limitations that exist around impediments moving material abroad. Having a directory would facilitate direct contact with institutions and future, potential exchange of material to improve representation of our collections. Researchers who are users of natural history collections would be the most benefited, as they would have a catalogue of collections which they can contact (through email with active staff, phone or website), with basic data about their thematic or taxonomic coverage.
