We originally featured the Catalogue of Life in the 3-30-2018 Scout Report, and since then this resource has added approximately 200,000 species to its vast index. For researchers and students interested in global biodiversity, the Catalogue of Life is an index consisting of over 1.8 million species from around the globe. The catalogue collects this information from over 200 taxonomic databases, which are peer-reviewed by a team of experts. Visitors will find a link to the most recent edition of the catalogue, (updated monthly) from the site's homepage. Users can search the catalogue by keyword or browse by taxonomic tree (e.g. Animalia, bacteria, viruses) or by taxonomic classification (e.g. phylum, genus, species). The catalogue is available in twelve languages, including Spanish, Chinese, Portuguese, and Russian. Those interested in using the Catalogue of Life may want to start by taking a look at the resources page, which includes a user's guide and frequently asked questions about the index.
