Organizations that want to use the registry should be aware of the criteria, for including digital material in the registry.
•Material must be digitized according to documented standards and best practices;
•Must reside in professionally-managed storage
•the organization must have an intent to preserve the digital material for the long term (decades or centuries – people will, we hope, come to rely on this, so it represents a long-term commitment ); and
•there must be a use copy of the digital resource available to the general public, though the use copy need not be free.

A registry record contains information about the digital master and the use copy.
