Wiki projects, including Wikipedia, Wikimedia Commons, Wikidata, contain the information that powers the web. Wikipedia is the fifth most-visited website in the world. To edit a Wiki project is to contribute content that could, potentially, be viewed by thousands or even millions of people over time, both on Wiki sites and on sites like Google and Facebook, which harvest data, including media, from Wiki sites.
For the #HerNaturalHistory campaign, the LuEsther T. Mertz Library of the New York Botanical Garden and the Smithsonian Libraries held three crowd-sourcing citizen science/citizen humanities events in March of 2019. These events were intended to bring new editors to Wiki projects, have editors add information about female scientists to Wikipedia, and have editors add information to BHL collections on Flickr and in Wikimedia Commons utilizing the Wikidata knowledge base/database/catalog.
