The Catalogue of Life Partnership
In June 2001 the Species 2000 and ITIS organisations, that had previously worked separately, decided to work together to create the Catalogue of Life, now estimated at 1.9 million species (Chapman, 2009). The two organisations remain separate and different in structure. However, by working together in creating a common product, the partnership has enabled them to reduce duplication of effort, make better use of resources, and to accelerate production. The combined Annual Checklist has become well established as a cited reference used for data compilation and comparison. For instance, it is used as the principal taxonomic index in the GBIF and EoL data portals and recognised by the CBD.
