What is the National Archives Catalog?

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 and the Presidential Libraries. The Catalog also allows users to contribute to digitized historical records through tagging and transcription.

What does the Catalog contain?

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.

How to Search

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.

Viewing Search Results

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. 

1. By default, 20 results are shown on the first page. To view more results, click on page numbers or the arrows to advance to additional pages. 

2. To increase the number of results displayed on each page, select the Results per page drop-down arrow.

Sorting Search Results

By default, the search results are ordered by the most relevant first. Change the sort order by choosing an alternative from the drop-down Sort by button at the top of the search results screen.

The sort options include:

  • Relevance (default)
  • Title
  • National Archives Identifier

  • Date (year ranges)

Search refinements are provided on the left side of the search results page.

  2. On the results page, click on one of the search refinement options on the left side of the screen. The search will be refined further based on the new criteria added.
  3. The selected refinement will be displayed below the Refine, followed by an "X" (e.g., Refinements: Type of Archival Materials: Moving Images x). You may select additional refinements to further narrow your search results.
  4. Click on the "X" following a refinement to remove the refinement and return to the original set of search results.

Searching Within a Record Group, Series, or File Unit

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.

Using the Advanced Search

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.
