Pilsbry's land snail of NA may still be available from the Academy of
Natural Sciences at Philadelphia.
Hubricht's book was published in Fieldiana, a journal of the Field Museum,
Chicago.
Burch's book on NA freshwater snails was available from Malacological
Publications, Hamburg, MI  48139  Contact the Museum, UM in Ann Arbor, MI
to find out more.
Same with Burch's books on freshwater clams.
Burch's How to know.......is out of print, as is Baker's Illinois book.
Good luck on these last two.....the others will just take a little leg work
and the ability to cover a check......Kurt
