  • The National Archives Catalog is the online portal to the records held at the National Archives, and information about those records. It is the main way of describing our holdings and also provides access to electronic records and digitized versions of our holdings. 

    The Catalog searches across multiple National Archives resources at once, including archival descriptions, digitized and electronic records, authority records, and web pages from Archives.gov and the Presidential Libraries. The Catalog also allows users to contribute to digitized historical records through tagging and transcription.
