Encyclopedia of Life (EOL) is a free, online encyclopedia that intends to document all of the 1.8 million living species known to science. It is being compiled from existing databases as well as with contributions from experts and non-experts globally. It aims to build an expandable page for each species, including images an other multimedia. The project is backed by a $50 million funding commitment, led by the MacArthur Foundation and the Sloan Foundation.
While EOL's goal is to develop of species pages for every known species, it does not emphasis phylogenetic information, and currently uses the more traditional Linnean taxonomy inspired domain, kingdom, phylum, class, order, family, genus, species classification scheme. Instead, phylogenetic information will continue to the focus of the complementary Tree of Life Web Project.
