The New York Public Library’s digital preservation activities are a shared responsibility among its information technology and digital initiatives groups, curatorial areas, and the Preservation Division. Policies and procedures are developed by Library staff to further the Library's mission and commitment to the long-term stewardship of its digital assets.
Management of the large quantity of content - images, metadata, and machine-readable text (obtained through OCR) - generated through the Library’s participation in the National Digital Newspaper Program
(NDNP) serves as a pilot for the Library’s digital repository.
The Library was one of six founding participants and the representative for the State of New York in the NDNP, a collaborative effort funded by the National Endowment for the Humanities
(NEH) and sponsored by the Library of Congress
. The long-term program serves to digitally preserve and provide enhanced access to United States newspapers published between 1836 and 1922, with a goal of nation-wide participation. The titles selected for NDNP, the New York Evening World
and the New York Sun
, had been previously microfilmed or otherwise preserved through the NEH-sponsored United States Newspaper Program
(USNP). Chronicling America
, a product of NDNP, is a web-based, searchable database of U.S. newspapers, providing historical information, and features a dynamic interactive viewer for searching, navigating, and magnifying the digitized pages. Participating in three grants cycles, the Library has digitized nearly 400,000 pages of the New York Evening World
, from 1887 to 1922, and the New York Sun
, from 1859 to 1920 (which eventually became the Sun and New York Herald
after a series of merger-related title changes).
