(This is not an official statement of policy by the Department of State; it is intended only as a guide to the contents of this volume.)
Since 1861, the Department of State’s documentary series Foreign Relations of the United States has constituted the official record of the foreign policy and diplomacy of the United States. Historians in the Office of the Historian collect, arrange, and annotate the principal documents comprising the record of American foreign policy. The standards for the preparation of the series and the general deadlines for its publication are established by the Foreign Relations of the United States statute of October 28, 1991 (22 USC 4351, et seq.). Volumes in the Foreign Relations series are published when all the necessary editing, declassification, and printing steps have been completed.
The documents in this volume are drawn from the centralized indexed files of the Department of State and the decentralized Bureau, Office, and other lot files of the relevant Departmental units. The volume also includes records from the Department of Defense and the Central Intelligence Agency. In addition, the editor made extensive use of the Presidential and other papers at the Lyndon B. Johnson Library in Austin, Texas.
Almost all of the documents printed here were originally classified. The Information Response Branch of the Office of IRM Programs and Services, Bureau of Administration, Department of State, in concert with the appropriate offices in other agencies or governments, carried out the declassification of the selected documents.
