I think that one of the issues that is
lost in this particular case is that the original poster stated that the
material had been given to several other institutions as well, and additionally
had questionable factual.
The original institution in question
obviously had their sound reasons for de-accessioning this item. In our
collections policy, we clearly state that the steps before we move to “witnessed
destruction”, and those include attempting to find another home for the
item in question.
The trained, professional museum staff of
this organization obviously took all of the information they had about the
item, (including the dubious information and the fact that it was duplicated in
other holdings) and decided to dispose of it. The volunteer donating it to the
new organization might not have conveyed all the information, and that would
have been a problem.
I do not think the original poster wanted
to call into question their de-accessioning process, simply what to do with a
volunteer that had clearly over-stepped their boundaries.
