In early 2005 the National Endowment for the Humanities announced the creation of the National Digital Newspaper Program . Building on the foundation of the USNP, this new program will digitize and make accessible newspapers from all U.S. states and territories published between 1836 and 1922. The first round of six state projects began in mid-2005 with more states added each year.
NEH created the United States Newspaper Program (USNP) in the early 1980s in response to needs expressed by scholars studying the nation's history, politics, and sociology, as well as other areas of common interest such as genealogy and local history. NEH chose to concentrate on newspapers because they provide one of the largest and most comprehensive bodies of original materials conveying the story of our country.
In the mid-1980s, the first grants for state-wide USNP projects were awarded. Grants were given to historical societies, and state, public, and academic libraries. The Michigan Newspaper Project was based at the Library of Michigan.
Projects were funded in every state, and in the District of Columbia, Puerto Rico and the U.S. Virgin Islands.
