I'm a college student who is researching U.S. foreign policy during World War I. When I look in the Catalog, there are references to Record Groups, but I don't know exactly what that is. Can you help, please?
Permanent federal records held by the National Archives are arranged in a hierarchy to ensure that records are organized and attributed to the government agency that created or maintained them. A Record Group is the highest level of arrangement at the National Archives; Record Groups typically comprise the records of a major government entity, usually a bureau or an independent agency. See how NARA’s Record Groups are organized.
