. The database is searchable by key terms, state, language, time period, or newspaper. The ''Chronicling America'' website contains digitized newspaper pages and information about historic newspapers to place the primary sources in context and support future research. It hosts newspapers written in a variety of languages. In selecting newspapers to digitize, the site relies on the discretion of contributing institutions. The project describes itself as a "long-term effort to develop an Internet-based, searchable database of U.S. newspapers with descriptive information and select digitization of historic pages." Local participants in the project receive two-year grants to scan approximately 100,000 newspaper pages, primarily from microfilm. For newspapers that are not digitized, the website directs users to library locations that are known to have the desired records available.
