The technical guidelines for all awards describe the specific technical requirements for inclusion of digital content in Chronicling America. All specifications must be met for awardees content to be accepted; all data will be verified and reviewed by the Library of Congress.
NDNP supports a consistent technical specification for digital newspaper reproductions and associated metadata in order to maintain parity of services for materials from a variety of institutions and collections and to support the “best practices” of today’s understanding of digital preservation needs.
