Even though a work is read by a large group of people, it is still unpublished where it is held confidential and the authors do not relinquish control over their copies of the work. See College Entrance Examination Board v. Cuomo, 788 F. Supp. 134, 139-41 (N.D.N.Y. 1992) (finding that administered secure tests were necessarily unpublished because author did not relinquish control and finding for author on second fair use factor). Plaintiffs have adequately demonstrated that the Exhibit B Advanced Technology works are kept confidential using tight security measures.
