National Archives and Records Administration Catalog

Online Resources
Access the National Archives Catalog.

Introduction
The National Archives Catalog provides online access to the National Archives and Records Administration's (NARA) holdings. National Archives facilities include locations in the Washington, DC area, Regional Archives and Federal Record Centers across the United States, and Presidential Libraries. Not all of NARA's records are described in the catalog, but NARA is working towards complete coverage. Researchers can search the catalog by keyword, dates, person name, topic, physical location of records, National Archives Identifier (NAID) and digitized images. The catalog supports basic and advanced search capabilities. Most records described are at the series level within record groups. Catalog search results also include scanned textual images, NARA websites, maps, photographs, motion pictures, blog posts, etc. The catalog can also be searched at About the National Archives Catalog.

The catalog has recently been redesigned. The following archives article will describe the new features. [Welcome to the new https://www.archives.gov/research/catalog/ngc-preview National Archives Catalog.]
