Wait, a quick search shows that "The Mind Managers" might be a book by Fred Turner, a Stanford professor, not Herbert Schiller. Alternatively, Herbert Schiller wrote "The Media Establishment," but "The Mind Managers" isn't one of his known works. There's also a possibility the user mixed up names. Another thought: perhaps it's a PDF titled "Herbert Schiller the Mind Managers" by an unknown author. Maybe it's a lesser-known scholar or part of a course syllabus.
