Geological collectors and curators have been using attached labels for centuries without too much problem. I've handled specimens with labels applied in the late eighteenth century that seem as good as the day they were made and obviously have a long future ahead of them. OK, in time some do fall off, but numbers written more directly on specimens don't necessarily last too well either. I've seen numbers on various types of objects (ceramics, glass, wood, paper, etc.) that have faded or worn away after only a few decades, or less. But just looking at how you mark is not enough. There's as much to be said of where you apply the mark as what medium you use. And making sure that the writer has a steady and legible hand. And ensuring that you have a regular regime for systematic or spot checks on object marks as part of an on-going collections care routine. Michael Cooper, Registrar, Nottingham Museums
