Catalogue of Life (COL) is a collaboration bringing together the effort and contributions of taxonomists and informaticians from around the world. COL aims to address the needs of researchers, policy-makers, environmental managers and the wider public for a consistent and up-to-date listing of all the world’s known species. COL also supports those who need to manage their own taxonomic information and species lists.
