best literature for identifying shells

[mdmshellbooks]

Hi,
The best books for quick identification of worldwide shells are the two volumes, "Encyclopedia of Marine Gastropods" and "Encyclopedia of Marine Bivalves" (they can be purchased separately) and in the first show 5500 species and in the second volume 2000 species. The "Compendium" shows about 5200 species. The "Encyclopedias" are the best selling books on my website mdmshellbooks.com and while the identifications are not all perfect they are usually correct and unlike the "Compendium" the photos are sharp and large in size.
