We have both a permanent and a study collection. Permanent
collection objects are accessioned and are not provided for
hands-on use. As additional gifts are offered, we often allocate
duplicate or damaged items to the study collection. This
collection is for loans to low security sites like public and
university libraries, etc. We also loan these objects for
hands-on activities in schools, science fairs, etc. The items are
not formally accessioed (however, they are given via deed of
gift). I mark each piece with tiny letters in ink, "STUDY." When
an item in this collection is broken or damaged from use, it is
discarded. Amazingly, few items get damaged so our study
collection continues to grow.
Hope this is helpful.
