GSA Form 1566: Top Secret Control Sheet

GSA Form 1566, Top Secret Control Sheet, is a General Services Administration form, Rev. 9-74, marked TOP SECRET at the foot of the page. GSA hosts it in its forms library.

The sheet goes with TOP SECRET material and logs each person having access to the attached document. For every person it records a printed name, office and signature, and the time and date the material was received and released. A control number, copy number and organizational unit go at the top.

The form says the attached material contains information whose unauthorized disclosure would cause EXCEPTIONALLY GRAVE DANGER to the nation, and that special care in handling, custody and storage must be exercised in accordance with the security regulations of the General Services Administration.
