This database comprises records related to more than 500,000 invertebrate lots maintained in the Malacology Department at the Academy of Natural Sciences of Philadelphia. These include original computer records for material entering the collection since 1976; records digitized from the handwritten catalogues, which were started in 1889; an inventory, started in 2011, that has recorded the current placement in the collection of more than 412,000 lots, and images of specimens and labels, particularly for type lots.
