I’m curious about the One World Collection initative, its results and this topic.Between 2017 and 2018, the staff dedicated to working with collections (at the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”) were asked to estimate the number of specimens in the collections (according to certain taxonomic criteria). I am sure that many people present here went through the same process. Can we use this information for this Collections Catalogue initiative? Do we have any lessons learned with the OWC? Or maybe we need to use a different kind of scale?
