The 9th edition of Bergey's Manual of Determinative Bacteriology serves as a reference to aid in the identification of unknown bacteria.
The arrangement of the book is strictly phenotypic, with no attempt to offer a natural higher classification. The arrangement chosen is utilitarian and is intended to aid in the identification of bacteria. The bacteria are divided into 35 groups. These groups are not meant to be formal taxonomic ranks, but are a continuation of Bergey’s tradition of dividing the bacteria into easily recognized phenotypic groups.
Bergey's manual of systematics of archaea and bacteria (2015), an online book, replaces the five-volume set.
