What is a Record Group?
A record group, the basic unit of archival control, is a body of organizationally related records designated by a number and the name of the federal agency, bureau, or activity that created or received them. The National Archives at Denver has 96 record groups, representing federal agencies, bureaus, and other administrative units including federal courts in Colorado, Montana, New Mexico, North Dakota, South Dakota, Utah, and Wyoming.
