Species 2000Species 2000 is a ‘federation’ of database organizations working closely with users, taxonomists and sponsoring agencies. Each database covers all known species in the group, using a consistent taxonomic system. The participating databases are widely distributed throughout the world and currently number 52. The program in partnership with the Integrated Taxonomic Information system (ITIS) of North America currently produces the Catalogue of Life. This is used by the Global Biodiversity Information Facility (GBIF, http://www.gbif.org/) and Encyclopedia of Life (EoL) as the taxonomic backbone to their web portals. Species 2000 receives funding from GBIF.
