Members of the Nederlandse Malacologische Vereniging are likely to be familiar with distributional studies carried out by the Conchological Society of Great Britain & Ireland. The Society has been in the forefront of recording the distribution of marine Mollusca in British waters and the north-east Atlantic. The publication of two national Distribution Atlases in 1982 and 1990 effectively marked the end of one era of recording in British waters. Recording efforts are now being directed towards more detailed local and regional projects.
