The World Biodiversity Database (WBD) is a continuously growing taxonomic database and information system that allows you to search and browse a number of online species banks covering a wide variety of organisms. The 17 species banks accessible through the WBD offer taxonomic information, species names, synonyms, descriptions, illustrations and literature references, as well as online identification keys and interactive geographical information systems. The WBD currently includes 24514 unique taxa, plus 3702 synonyms.

Contains information on over 136,000 plant taxa of conservation importance based on 19,000 data sources. The database may be searched by common or scientific name (family, genus or specific epithet).

The Fauna Europaea project (EVR1-1999-20001) has been funded by the European Commission for a period of four years (1 March 2000 - 1 March 2004) within the Fifth Framework Programme (5FP). Fauna Europaea has assembled a database of the scientific names and distribution of all living multicellular European land and fresh-water animals. Experts in taxonomy have provided data of all species currently known in Europe. Together these data have formed a huge database, which will be accessible to everyone. The University of Amsterdam has coordinated the project, assisted by the University of Copenhagen and the National Museum of Natural History in Paris.

Netherlands' Biodiversity Information Facility (NLBIF) is the Dutch Node for the Global Biodiversity Information Facility, GBIF. GBIF aims at facilitating access to biodiversity information at a world-wide scale.

The Information Center for the Environment, in conjunction with the National Park Service, developed preliminary databases of vascular plant and vertebrate animal species reported to occur within lands managed by the U.S. National Park Service.
