I agree with what Richard has said here most strongly....when curating the material from Vindolanda, I have followed the American Museum style, writing both context code and the unique catalog number on each and every item. The only exceptions to this have been the material we have been recovering via sieving/flotation -- bones of tiny species of birds, mammals, amphibians, and fish that it would just be physically impossible to write on. I have put these specimens in glass or (in some cases) plastic vials. Even the glass vials have plastic screw-on tops, so as Richard notes they are perishable, but it's the best we can currently do. Into the vial with the specimen goes a label written with a Sharpie permanent marker on a little strip of Tyvek paper. This is dangerous because if somebody comes to study the material and they break the lab rule and have more than one vial open at one time, specimens could get put back into the wrong vial and hence associated with the wrong number. To guard against this, I do three things: (1) take index photographs of each and every tiny specimen (we have a wonderful videophotomicroscope in the lab which makes this job a snap); (2) get the catalog typed up and backed up/cut to disk ASAP after assigning numbers to specimens; (3) forbid anybody else to work with our microfauna (i.e. open the vials) until I've got 'em published!!!!
