Bergey's Manual of Systematic Bacteriology, one of the most comprehensive and authoritative works in the field of prokaryotic systematics is undergoing an extensive revision that will ultimately culminate in a five volume Second Edition. Arrangement of the content of the Second Edition follows the now familiar and well regarded phylogeny of the 16S rRNA gene, yet retains much of the layout of the First Edition. Volume 1, encompassing the Archaea, Deeply Branching and Phototrophic Bacteria was published in 2001. We are pleased to announce that work on Volume 2, The Proteobacteria, has been completed. This culminates a four year effort by Bergey's Manual Trust and more than 150 internationally recognized authorities to provide a comprehensive view of the Proteobacteria, the largest prokaryotic phylum. Encompassing 72 families and including descriptions of 425 genera and over 1875 named species, the volume will be subdivided into three sub-volumes: The Gammaproteobacteria (Part A), The Alphaproteobacteria (Part B) and the Beta-, Delta-, and Epsilonproteobacteria. Also included are new introductory chapters specific to the phylum.

Includes introductory chapters on classification of prokaryotes, the concept of bacterial species, numerical and polyphasic taxonomy, bacterial nomenclature and the etymology of prokaryotic names, nucleic acid probes and their application in environmental microbiology, culture collections, and the intellectual property of prokaryotes. The first Road Map to the prokaryotes is included as well as an overview of the phylogenetic backbone and taxonomic framework for prokaryotic systematics.
