Field notes
Its interface separates a classification tree from list, kana/ABC, color, and numbered views; visitors can filter entries by introductory, standard, or all-species sets, then expand the tree or zoom and pan. A “today’s stone” feature pairs a specimen with hardness, principal producing countries, and a short classification note. Sample captions credit photographers and link images to Wikimedia Commons under stated CC licenses.
