Six US federal agencies have worked together to develop an efficient system for naming and classifying all of nature's living organisms. As the basic currency of scientific research, management, and education, ITIS is "a database of the current names and classifications of all biota." The website is organized into three main sections: About ITIS (general overview), Data Access (how to query the ITIS database), and TRED (the taxonomic experts behind the ITIS database). The core of the site is the Data Access section, which describes how to locate, access, and download scientific names and other information for a taxon. The ITIS database may be queried by full or partial Scientific Name, Vernacular (Common) Name, or TSN (Taxonomic Serial Number). Typical returns are Scientific Name, Vernacular (Common) Name, TSN, Author, Taxonomic Rank, and Synonym Name or TSN; note that the review process is still underway, and information is constantly added. In addition to the database, users are instructed on how to submit data to the ITIS database or match a list of taxa to the ITIS Database. A final, useful feature is the Taxonomic Workbench (free for downloading), "a windows-based software tool for entry of taxonomic information into ITIS' relational database format." Information on how to participate in this extraordinary and ambitious effort is provided at the site.
