Dear Amanda, Chenhall's was designed to classify only man-made objects. We have quite a few natural history specimens so we added three additional categories to accommodate these with appropriate classifications within these categories. Since Museum-L does not allow attachments, I will post this addition to nomenclature on Musedocs which is a Yahoo Groups site. If you are not a member and don't wish to become one, let me know via e-mail and I will send you the attachment. Hope this helps.
