From the National Digital Newspaper Program website:
"The National Digital Newspaper Program (NDNP), a partnership between the National Endowment of the Humanities (NEH) and the Library of Congress (LC), is a long-term effort to develop an Internet-based, searchable database of all U.S. newspapers with descriptive information and select digitization of historic pages. Supported by NEH, this rich digital resource will be developed and permanently maintained at the Library of Congress. An NEH grant program will fund the contribution of content from, eventually, all U.S. states and territories."
