The Macrobenthos of the North Sea project was initiated by ETI and the Zoological Museum at the University of Amsterdam. It provides users with a complete and up-to-date catalogue of macrobenthic species, including reliable standardized identification guides. In a series of five CD-ROMs the biological diversity in the shallow-water macrobenthos of the North Sea (down to 100 m) is documented.
Volume I of this series contains detailed information on 525 species of the phylum Mollusca and the phylum Brachiopoda, including fully illustrated picture keys, glossaries of used terms and interactive distribution maps of the phylum Mollusca.

Sources for the information are manifold, but the major source is "The Marine Fauna of the British Isles and North-West Europa" (eds. Hayward and Ryland, 1990).
