Another challenge that visitors don’t often notice is that Curatorial staff must keep the collection organized, intact, and accounted for while allowing it to be accessible to visitors. Keeping the collection organized is a challenge as many artifacts have not been cataloged and this makes them difficult to track down. The annual inventory that Appomattox does helps to keep the collection organized and accounted for as staff must go search for those items to make sure they are not only present in the collection, but to make sure they are in the location the collections database ICMS says they are. If the location they are found in does not match the location indicated in ICMS, then this information must be updated. Keeping track of these artifacts is important as at some point they might be put on exhibit or be used for research by a contractor so organization is key. However, keeping the collection intact is another challenge. Everyday pests try to invade the collection and cause damage to collection items the park holds. For example, silverfish and book lice are potent pests as they may cause great damage to items made of paper such as letters, books, and other valuable materials in the APCO collection. To combat this, Curatorial staff put out sticky traps in various buildings in the village in order to catch these pests and stop any damage. Yet, even though these traps are meant to catch museum pests, every once in a while, a lizard may get caught in the traps unintentionally.
