CONFIDENTIAL MATERIAL
Confidential Material.
a. Classified security material. If a work appears likely to contain material classified by the Government as security information (usually identified by the marking "Top Secret," "Secret," or "Confidential", and sometimes bearing a notation that the material contains information affecting the national defense), the copies should immediately be turned over to the Security Officer, and we will ask the applicant to explain the confidential character of the material. A work containing classified security information will not be registered.
b. Other confidential material. When an applicant requests that the deposit copies be withheld from inspection by the public, we will inform him that registration cannot be made with such a restriction. [September 1954]
