This growing database will eventually become a comprehensive listing of all known species of organisms on Earth. (A partner with the Integrated Taxonomic Information System (ITIS) – see below) Includes genus, distribution, life zone, and links to online resources. Site visitors may search using common or scientific names or browse data via a taxonomic tree listing eight kingdoms: Animalia, Archaea, Bacteria, Chromista, Fungi, Plantae, Protozoa, and Viruses. Clicking on Taxonomic Classification leads to a search form with fields including Top Level Group (kingdom), Phylum, Class, Order, Superfamily, Family, Genus, Species, and Infraspecific Taxon.

American’s Wildlife Resource includes Field Guides to almost 6,000 plant and animal species and is the same data set used to create the printed Audubon Field Guides.

The Encyclopedia of Life (EOL) is an ambitious project to organize and make available via the Internet virtually all information about life present on Earth. At its heart lies a series of Web sites—one for each of the approximately 1.8 million known species. Each site is constantly evolving and features dynamically synthesized content ranging from historical literature and biological descriptions to stunning images, videos and distribution maps.
