Cold Storage Introduction

The NPS cold storage project is focused onthe preservation of cellulose film-based materials. Cold storage may be implemented using freezers or vaults. For smaller collections, you may want to consider using a standard houshold upright freezer. However, for larger collections, it becomes more cost efficient to consider using a vault.
