Crowdsourcing andco-curation froma natural historyperspective

Naturalis Biodiversity Center= (collection × research) + museum

40 million specimens

Also, T. rex.

● ‘Cognitive surplus’: to build a big collection together

● Networking: finding and binding amateurs and professionals

● Enrichment: gather object types not part of own (Naturalis) collection

Why do we crowdsource?

What to do when crowdsourcing?

Provide a shared goale.g. illustrating inter- and intraspecific diversity

Create a sense of connectedness

Make the shared goal social e.g. by

● acknowledging users● stand amongst your users● meetings between users● co-curating content● solving puzzles together

Connectedness: helping research(ers)

● Customization● Create feedback loops● Provide (new) insights● Personal progression

Allow for autonomy and mastery

Always

● provide shared goal (a purpose)● create a sense of connectedness● allow for autonomy and mastery

Also, be aware that

● content issues will arise● expertise can be a bottleneck, too

What to do when crowdsourcing?

Connecting species to specimens
