The National Digital Information Infrastructure and Preservation Program (NDIIPP) is like a library for digital information. It is a program created by the United States government to help keep important digital information safe and secure. This program makes sure that websites, videos, books, photos, and other digital information are available to people now and in the future. It does this by storing them in special libraries called "repositories". Repositories are places that keep digital information for a long time. That way people can access them even after many years.
