The Index to Organism Names (ION) is an extensive compendium of scientific names of taxa at all ranks in the field of zoology, compiled from the Zoological Record (later supplemented with content from Sherborn's Index Animalium) by its operators as a publicly accessible internet resource. Initially developed by BIOSIS, its ownership then passed to Thomson Reuters and is currently with Clarivate Analytics.
