. The database includes more than 84,000 entries of historic sites that are currently listed on the National Register, that were previously listed and later removed, or that are pending listing. The database includes approximately 45 pieces of data for each listed property. Accuracy of the NRIS database may be imperfect. For example, a 2004 paper addressed accuracy of spatial location data for part of the NRIS content.

History

Efforts to digitize the database began as early as 1968, but the database was not fully digitized until 1986. By 1994 it had come to be used in answering more than 4,000 public queries per year.

Availability

A search interface within the National Park Service's NPS Focus system provides access to a skeletal record of NRIS data, as well as to photographs and documents describing properties listed on the National Register. The skeletal record includes a simplified set of the information in NRIS about all sites listed through August 2012. The NPS Focus search screen allows searching by NRHP listing name or other property identifiers.
