National Digital Information Infrastructure and Preservation Program



• Develop a national strategy to collect, archive and preserve

the burgeoning amounts of digital content, especially

materials that are created only in digital formats, for current

and future generations.


• Architectures for persistent digital repositories (technology

infrastructure, component layers of service, etc.);

• Preservation technologies and tools (Web harvesting methods,

techniques for normalizing heterogeneous objects, algorithms for

proving authenticity, audit mechanisms, interoperability, and large

scale back-up and recovery mechanisms);

• Attributes of archived collections (methods for determining and

validating completeness and closure of preserved digital objects);

• Policy and economic models (roles and responsibilities, access

services, legal agreements, and balancing private interests with public



• Convene stakeholders, coordinate collaborative research

We are a worldwide library cooperative, owned, governed and sustained by members since 1967. Our public purpose is a statement of commitment to each other—that we will work together to improve access to the information held in libraries around the globe, and find ways to reduce costs for libraries through collaboration.
