GBIF—the Global Biodiversity Information Facility—is an international network and Research Infrastructure funded by the world’s governments and aimed at providing anyone, anywhere, open access to data about all types of life on Earth. The GBIF network of participating countries and organizations, working through participant nodes, provides data-holding institutions around the world with common standards and open-source tools that enable them to share information about where and when species have been recorded. This knowledge derives from many sources, including everything from museum specimens collected in the 18th and 19th century to geotagged smartphone photos shared by amateur naturalists in recent days and weeks.
