National Digital Newspaper Program (NDNP)
http://www.loc.gov/ndnp/

The National Digital Newspaper Program (NDNP) is a partnership between the NEH and the Library of Congress to provide enhanced access to United States newspapers. . Ultimately, over a period of approximately 20 years, NDNP will create a national, digital resource of historically significant newspapers from all the states and U.S. territories published between 1836 and 1922. This searchable database will be permanently maintained at the Library of Congress (LC) and be freely accessible via the Internet. An accompanying national newspaper directory of bibliographic and holdings information on the website will direct users to newspaper titles available in all types of formats. LC will also digitize and contribute to the NDNP database a significant number of newspaper pages drawn from its own collections during the course of this partnership between NEH and the Library. The two agency partners launched a prototype of this digital resource, “Chronicling America: Historic American Newspapers,” in March 2007.
