Bergey's Determinative Manual is meant for the identification of bacteria that are already cultured and described. The manual is arranged by phenotypic information. Once you have completed all of the morphological, cultural characteristic, and differential tests for your unknown organism, use a dichotomous key to identify a possible genus for your organism.
Bergey's Systematic Manual helps you classify unknown bacteria. Only Volume 2: the Protobacteria is available online. Otherwise you need to use the pront version
