Theory of Preservation
Preservation can be thought of as communication with the future. Information that is understood today is transmitted to an unknown system in the future where it will be interpreted and displayed. The future system may have not only different hardware and software, but also different standards for encoding information. Effectively, we need to send into the future not only the information (records), but also a description of the environment that is being used to manage and read those records.

"...let us save what remains: not by vaults and locks which fence them from the public eye and use in consigning them to the waste of time, but by such a multiplication of copies, as shall place them beyond the reach of accident."
— Thomas Jefferson, February 18, 1791
