Founded in 1997 by Jean P. Euzéby.

The List of Prokaryotic names with Standing in Nomenclature (LPSN) provides comprehensive information on the nomenclature of prokaryotes and much more. Navigating LPSN is easy.

LPSN is a free to use service founded by Jean P. Euzéby in 1997 and later on maintained by Aidan C. Parte.

As of February 2020, the regularly augmented LPSN database at DSMZ is the basis of this new LPSN service. The new database was implemented for the Type-Strain Genome Server and augmented in 2018 to store all kinds of nomenclatural information. Data from the previous version of LPSN and from the Prokaryotic Nomenclature Up-to-date (PNU) service were imported into the new system. PNU had been established in 1993 as a service of the Leibniz Institute DSMZ, and was curated by Norbert Weiss, Manfred Kracht and Dorothea Gleim.

As of December 2023, LPSN is recognized as Global Core Biodata Resource.
