Congress authorized the Library of Congress to undertake the National Digital Information Infrastructure and Preservation Program (NDIIPP) to prevent the loss of our digital heritage. This work, as with all digital preservation activities, is challenging because of technical issues and also because traditionally there have been few effective collaborative mechanisms to leverage resources and expertise. NDIIPP aims to address both issues while also ensuring the preservation of at-risk digital content. Concrete steps have been taken recently with the establishment of eight partnership consortia, each of which has committed to working with the other and the Library on collaborative digital preservation initiatives. The eight consortia represent the formal launch of an NDIIPP national network of preservation partners. Currently, NDIIPP is exploring how best to involve states and territories in the network.
