Bibliography for the Identification of North American Freshwater
Snails. This is Rob Dillon's compilation of guidebooks, keys,
monographs, systematic reviews, regional surveys, checklists, and any
other published reference material potentially useful for identifying
our freshwater gastropod fauna, 1900 - present. It is available
in three forms:

the 67 species of freshwater gastropods inhabiting Atlantic Drainages
from Georgia to the New York line. From that page you can
follow links to several essays I have posted on the FWGNA blog
regarding this thorny topic.
