Regarding the labeling of artifacts, one problem I could see with the avery labels would be their size. The space available on the artifact could be very small and not necessarily flat, while something like a bar code would need a standard size flat surface to be scanned. The labels would also not stick to every surface. Also, instead of using clear nail polish, clear Soluvar brand varnish is good. Over time nail polish does begin to flake off, the Soluvar won't damage artifacts and won't flake off. It can also be easily removed with naptha or a similar solvent. I think that a base coat of Soluvar, permanent ink (I've used Staedtler pens), and a top coat of Soluvar, is what's currently recommended by the American Association of Museums. Hope this helps.
