Hello!

The Pilsbry monograph "Land Mollusca of North America (North of Mexico)"
Vol I, part 1 & 2 and Vol II, part 1 & 2 (a 4 book set) is available from
the
Academy of Natural Sciences of Philadelphia. The pubs website page is at;

http://www.acnatsci.org/research/index.html?/scipubs/index

The books are listed in the bibliography table as follows;


 No. 3
        Pilsbry, Henry A. 1939, 1940,
        1946, 1948. Land Mollusca of
        North America (North of
        Mexico). Two volumes, four parts.
        573 pp., 419pp., 520pp., 592 pp.
        Respectively.
                                     Price per part:
                                     $35.00

I do not know if they are soft or hard cover. I obtained my set some time
ago
and had them bound. However I think the Academy used to also sell them
hard bound and soft bound.

Later,
