They are considered "expendable" in that if they are destroyed over time, there is little important loss to research. However, they may have monetary value. The collections are for older kids and adults to use for serious studies. They are expected to last well over 10 years (hopefully over a 100) despite public access. (that does not just refer to durability, but careful management and handling by the public of more delicate items. These items, while non-accessioned, are catalogued and otherwise treated like a regular part of the museum's collection. >> I developed a similar policy for my museum collections, but am struggeling with a way to track them. Do you assign any types of numbers & how do you keep them seperated from the accessioned collections?
