The National Archives & Records Administration (NARA) is one of the single largest archives in the world. As of 2020, NARA provides public access to 115 million pages of documents. The archives are searchable in a variety of ways, such as a simple keyword search (e.g. Thailand, World War II, Sarit Thanarat, etc). Searches can also be conducted using a broad Record Group Cluster search. Record groups correspond to the specific federal agency that produced, or came into possession of the document(s) in question. Researchers can also conduct a more directed search by focusing on specific record groups (RG), for example:
- RG 59-Department of State records
- RG 84-Foreign Service Posts
- RG 263-Central Intelligence Agency
- RG 576-Director of National Intelligence
- RG 226-Office of Strategic Services
- RG 472-U.S. Forces in Southeast Asia, 1950-1975
