Preservation Calculator

This morning, I found the preservation calculator at

It's very useful for us.

Preservation Calculator is a planning and analysis tool for collection storage environments in libraries, archives, and museums. Use it to:

• learn how temperature and RH affect organic objects in storage
• evaluate a given storage condition
• compare one storage condition to another
• plan new storage conditions
