(1) Determine that access is clearly consistent with the interests of the national security; and
(2) Take appropriate steps to assure that classified information or material is not published or otherwise compromised.

The Archivist of the United States shall have authority to review and declassify information and material which has been classified by a President, his White House Staff or special committee or commission appointed by him and which the Archivist has in his custody at any archival depository, including a Presidential library. Such declassification shall only be undertaken in accord with:
(i) The terms of the donor's deed of gift;
(ii) Consultations with the Departments having a primary subject-matter interest; and
(iii) The provisions of Sec. 11.5(c).
