Prokaryotic Nomenclature Up-to-Date (PNU) is a compilation of all names of Bacteria and Archaea which have been validly published according to the Bacteriological Code since
1. Jan. 1980, and nomenclatural changes which have been validly published since. It will be updated with the publication of each new issue of the International Journal of Systematic and Evolutionary Microbiology (IJSEM).
A more detailed overview of the mechanisms of valid publication of a name according to the Bacteriological Code can be found at: dx.doi.org/10.1099/ijs.0.64780-0, see also Naming of bacteria and Deposit of a proposed type strain.
The Approved Lists (1980) contain more than 2200 names at the genus level and below and 124 names of higher taxa. Validation Lists and taxon descriptions in the IJSB/IJSEM have been published regularly since. The total number of validly published names of prokaryotes increased to over 14800 species names and over 2600 genus names since (August 2015).

Prokaryotic Nomenclature Up-to-Date was established at the DSMZ by Norbert Weiss, Manfred Kracht and Dorothea Gleim. After a reconstruction of the service, PNU is now maintained by Privatdozent Dr. Markus Göker and a team of curators and computer scientists.
