The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, '' Encyclopedia of Life'', and the Global Biodiversity Information Facility. The Catalogue currently compiles data from 165 peer-reviewed taxonomic databases that are maintained by specialist institutions around the world. the COL Checklist lists 2,067,951 of the world's 2.2m extant

Structure

The Catalogue of Life employs a simple data structure to provide information on synonymy, grouping within a taxonomic hierarchy, common names, distribution and ecological environment. It provides a dynamic edition, which is updated monthly (and in which data can change without tracking of those changes) and an Annual Checklist, which provides a dated, verifiable reference for the usage of names and associated data. Development of the Catalogue of Life was funded through the Species 2000 europa (EuroCat), 4d4Life, i4Life projects in 2003–2013, and later by the Naturalis Biodiversity Center, Leiden, the Netherlands and Species Files group at Illinois Natural History Survey in Champaign-Urbana. Current people governing the CoL, contributors, Updated as required. and other relevant information which changes over time, are listed on the CoL website.

Usage

Much of the use of the Catalogue is to provide a backbone taxonomy for other global data portals and biological collections. Through the i4Life project, it has formal partnerships with Global Biodiversity Information Facility, European Nucleotide Archive, Encyclopedia of Life, European Consortium for the Barcode of Life,

, and Life Watch. The public interface includes both search and browse functions as well as offering multi-lingual services. The Catalogue listed 300,000 species by 2003, 500,000 species by 2005, and over 800,000 species by 2006. , the Catalogue listed 1.9 million extant and extinct

. There are an estimated 14 million mainly unpublished species; however, this number is uncertain as there is a lack of data on the possible number of undescribed insects, nematodes, bacteria, fungi and many others.

of life which included some sectors not yet represented in the published ''Catalogue''. In the same year, the Catalogue of Life, Barcode of Life Data System, Biodiversity Heritage Library, Encyclopedia of Life, and the Global Biodiversity Information Facility (GBIF) met to consider building a single shared authoritative nomenclature and taxonomic foundation "Catalogue of Life Plus" that could be used to order and connect biodiversity data, including content not yet in CoL but available via other sources, to serve both the users of the present ''Catalogue'' and users of extended taxonomic content (such as GBIF) using a common infrastructure. COL+ will develop a clearinghouse covering scientific names across all life, provide a single taxonomic view, and provide an avenue for feedback from content authorities. The CoL is developing in conjunction with the Global Species List Working Group to avoid replication and work towards an authoritative global list of species.
