E-Reference Subject Specific: U.S. National Security

The Foreign Relations of the United States series presents the official documentary historical record of major U.S. foreign policy decisions and significant diplomatic activity. The series, which is produced by the Department of State's Office of the Historian, began in 1861 and now comprises more than 450 individual volumes. The volumes published over the last two decades increasingly contain declassified records from all the foreign affairs agencies.

This digital facsimile of Foreign Relations of the United States is a project of the University of Wisconsin-Madison Libraries in collaboration with the University of Illinois at Chicago Libraries. This is a nearly complete run from 1861-1960 with missing volumes being added as they can be acquired and processed. The FRUS series, including post-1960 volumes, is available online on the State Department's Office of the Historian's website.
