The National Archives and Records Administration (NARA) acquires, preserves, and makes available for research the records of enduring value that were created or received by organizations of the executive, legislative, and judicial branches of the Federal Government. Records in the custody of the National Archives date from pre-federal times to the present. Most of the records are textual, but they can come in a wide variety of media, such as microfilm, maps and charts, architectural and engineering plans, aerial photographs, motion picture reels, video recordings, sound recordings, computer data sets, or still pictures.
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, and authority records. The Catalog also allows users to contribute to digitized historical records through tagging and transcription.
The Catalog currently contains archival descriptions of the National Archives’ holdings, authority records, and millions of digitized and electronic records. Over 95% of the National Archives’ holdings are described at the series level.
How are records in the Catalog organized?
Records described in the Catalog are organized according to NARA’s archival hierarchy, which is defined in the Lifecycle Data Requirements Guide (LCDRG) - NARA’s standard for archival description.
Record groups and collections are the highest level of archival description. Record groups most often contain accessioned records from federal agencies. Collections are generally made up of non-federal records that were donated to NARA, usually from presidential administrations.
Beneath the record group or collection is the series. A series is a group of records that are related as the result of being created, received, or used in the course of the same activity. The series is the descriptive level that is connected to the archival creator - the person or organization who created and/or maintained the records.
And beneath the series are file units or items. File units contain a more specific collection of related records within a series. A file unit often contains multiple discrete records, for example a grouping of memos. File units are always contained by series, while items can be contained by either series or file units. An item often reflects a specific record, for example a single memo. Both file units and items can contain digital objects, such as digitized pages produced from analog holdings.
The Catalog searches across multiple National Archives resources at once, including archival descriptions, digitized and electronic records, optical character recognition (OCR) text of digitized textual records, authority records. The Catalog also allows users to contribute to digitized historical records through tags, comments, and transcriptions, which are also searchable in the Catalog.
We do not hold records of state, county, city, or town governments, or of churches or other private institutions. Therefore, we do not have:
- Vital records - These most commonly refer to records such as birth and death certificates, marriage licenses and divorce decrees, wills, and the like. These records are created by local authorities, with possible exceptions for events overseas, in the military, or in the District of Columbia. They are not considered Federal records; therefore, they are not held by NARA.
- Information about applying for tribal membership. Membership is determined by the individual tribes.
- Records from state or county courts.
- State militia records. For these records, you will need to contact the appropriate State Archives.
Records that are not open for public access may be described in the Catalog; however, digital copies of restricted and unprocessed records will not be available in the Catalog. This includes:
- Information to help locate living individuals. The records in the custody of the National Archives are usually at least 20-30 years old, and information on living individuals is protected by the Privacy Act.
- Records that NARA has accessioned but not yet processed. See information about New Accessions.
- Presidential records that are within five years of the President leaving office. The Freedom of Information Act (FOIA) applies to the Presidential Records Act (PRA) five years after the President has left office. NARA uses this time to begin to conduct archival processing and otherwise prepare for the onset of public access.
- Classified records and records undergoing review for declassification.
The number of digital images in the catalog increases almost daily as a result of digitization. Even though the catalog contains hundreds of millions of digital images, it’s still just a small percentage of our holdings.
For best performance, Google Chrome, Microsoft Edge, and Safari web browsers are recommended when accessing and searching the Catalog.
Enter one or more keywords in the search box and press enter on your keyboard, or click on the magnifying glass icon.
If you enter more than one keyword, the Catalog combines them with an 'AND' so that the search obtains results containing all the keywords.
Catalog groups all search results together under "All Records" and ranks them based on their relevance to your search terms or parameters. All records include descriptions and descriptions that include digitized records. Users may select “Available to access online” to view only descriptions that include digitized records.

You may also perform a “search within” to search only for records contained within a particular Record Group, Collection, Series, or File Unit. To do so, navigate to the main description page for the Record Group, Collection, Series, or File Unit, and click on the blue hyperlink “Search within this Record Group/Collection/Series/File Unit” found in the black header below the title information.
This will take you to a page where you can search within using keywords in the search bar. Remove any existing words from the search bar and type a name, subject, or other keyword in the search bar.
Additionally, you can find another “search within” link in the Inside this… section of the description.
If you wish to specify your search more precisely than is possible using a basic search, click on the Advanced link next to the main search text box. Use the drop-down menus to further refine the advanced search options.
Please note that all of the Advanced search options except for Data Source only apply to Archival Descriptions, Archival Descriptions with Digital Objects, or Authority Records.

Please note that files containing raw data are usually only available for download. Please refer to the Technical Specifications Summary for details on the format of the files.
Many electronic record files do not contain a standard file extension that indicates the format or file type, so these files are usually not appropriate for viewing within the browser
Technical documentation is also available for viewing and/or downloading in the Catalog. This consists of the materials or information needed to interpret raw data or otherwise use the electronic records. These may include agency-prepared record layouts, field descriptions, code lists or meaning, user notes, and the sample questionnaires or forms the agency used to collect the data.
The Technical Specifications Summary is also provided as part of the technical documentation. This is a list of all the electronic records files for a Series or File Unit description that are available online. This list includes the technical metadata for each file, such as the byte count, file format, record length (for fixed-length records), number of records, and file identifiers and names. This metadata is usually needed for using the files after they have been downloaded.
