ITIS partners with taxonomic specialists, stewards, and data sources from around the world to provide a high-quality source of scientific names and their classification.

If you would like to partner with us to maintain a taxonomic group in ITIS that makes up your area of expertise, please reach out to us! Our Data Development Specialists will help you enter, review, and update data in ITIS using the Taxonomic Workbench (TWB).

We are actively looking for partners who want to trial a new version of the Workbench, TWB 6.0. You will be able to work within the ITIS beta environment and provide feedback to refine the functionality of TWB 6.0 before public launch. For further information contact us at
