The Natural History Museum, housing over 80 million specimens, is advancing its digitization efforts through tools like Inselect, an open-source application designed to expedite the digital cataloging of specimens from physical collections. Initially developed to identify and categorize insect specimens, Inselect significantly reduces the time required for manual processing, working within five to ten minutes per drawer compared to an hour manually. While initially tailored for insects, the application is adaptable for various digital cataloging projects and is compatible with Windows and macOS. This tool supports the museum's broader digitization plans, which include making larger artifacts like fossils and skeletons available online. By open-sourcing Inselect, the museum enhances accessibility to scientific collections worldwide and aligns with the Science International Open Data Accord, as demonstrated by projects like the University of Sheffield’s study on bird bill diversity using the museum's bird collection.
