Agencies whose documents are included in a volume participate in a declassification review. The Office can appeal the results of these reviews in an effort to release as much material as possible. The Office receives guidance from the Advisory Committee on Historical Diplomatic Documentation, a group of distinguished scholars from outside the U.S. Government. The Committee meets four times a year to review progress and make recommendations concerning the Foreign Relations series. Volumes on the Nixon administration are now being researched, annotated, and prepared for publication.
Recent volumes are also available on-line .
