But I do think the term item is better than the term copy, because I think Jennifer is right about copy implying that there is more than one of the same thing. There might be only one, or there might be multiple items which are parts as opposed to "copies." You have to add items to create parts, and it seems weird to say you are adding copies in that instance, since they are all different things.
