THE CENTRAL INTELLIGENCE AGENCY by John P. Quirk (Foreign Intelligence: $29.95; 256 pp.). This volume, billed as a photographic history, also contains extensive text generally lauding the CIA as "the foremost American intelligence organization and the most successful intelligence agency in the world." It contains two identical full-page color pictures of the latest CIA director, William Casey, and a foreward by a former director, Richard M. Helms, striking the theme carried forward throughout--that the agency is wonderful. "This volume," writes Helms, "will help all citizens understand why we must protect our open society by conducting secret operations . . . (and) that intelligence is necessary to the public good, and, by being necessary, becomes honorable."
