Science advances. Charles Darwin's (1859) On the Origin of Species
was one of the greatest scientific achievements the world has ever
known. It is also utterly obsolete today. That does not
mean that we ought to throw Darwin's work into the trash can.
It means that we must read it in the context of
subsequent scientific advance.
Similarly. Many of the
scientific works listed in the present bibliography of freshwater
gastropod research are quite old. Some predate the modern
synthesis. That does not mean that they have no value; it only
means that they must be contextualized. The older the work, the
more a user must understand about what has come after.
Bibliography for the Identification of North American Freshwater
. 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:
by author (complete through 2018, with 268 entries.)
Index (a subset, sorted into 8 subregions and a general North American category.)
Index (a subset, sorted into 14 families and a "general hydrobioid" category.)
Please email Rob Dillon (firstname.lastname@example.org
with any additions or corrections you might wish to contribute to this bibliography.
Bibliography Online. A searchable database including over
references on freshwater mollusks worldwide. This marvelous
is a collaborative effort by Kevin Cummings (Illinois Natural History
Survey), Art Bogan (North Carolina Museum of Natural Sciences), Tom
(the Ohio State University Museum of Biological Diversity) and Christine
(Illinois Natural History Survey). Funded by the National Fish

IV. On-line Collections.
- Almost all important freshwater gastropod collections worldwide are
searchable simultaneously through the Integrated Digitized
Biocollections resource. My query to the iDigBio database for
"Physidae and North America" on 17May19 returned 31,417 hits. For
a review of this remarkable facility, see my blog post of 22May19.
you visit a collection, however, it would be wise to check
the databases maintained by each museum locally, which tend
to be more current. Here are the top ten North American museums,
ranked by their North American records of the Physidae:
UMMZ - University of Michigan Museum of Zoology (5,492
).USNM - National Museum of Natural History, Smithsonian (5,417).
MCZ - Museum of Comparative Zoology, Harvard (3,619).
ANSP - The Academy of Natural Sciences of Drexel University (3,415).
FMNH - Field Museum of Natural History, Chicago (2,726).
FLMNH - Florida Museum of Natural History (2,083).
INHS - Illinois Natural History Survey (1,717).
CMNH - Carnegie Museum of Natural History, Pittsburgh (1,051). No local search.
NCSM - North Carolina Museum of Natural Sciences (824).
DMNH - Delaware Museum of Natural History (653). No local search.
