Revisionism And The Historical Black Out, 1953
https://www.heritage-history.com/site/hclass/secret_societies/ebooks/pdf/barnes_blackout.pdf
In this essay, Harold Barnes discusses the manner in which the true history of World War II has been systematically suppressed, and all 'revisionist' historians who contradict the official story are maligned and blacklisted. He discusses the way in which documents are withheld from revisionist authors, how revisionist histories are blacklisted by publishers, and systematically smeared by reviewers. Barnes reports on the discrimination suffered by several respected, 'progressive' historians, who refused to tow the pro-war line, including Charles A. Beard, William H. Chamberlin, and Charles Tansill.

In this short pamphlet John T Flynn describes the manner in which patriotic Americans who speak out against communist infiltration or criticize government insiders are systematically targeted and maligned by private gestapos. These smear agents spy on citizens and feed outrageous, misleading slander through radio, press, and other media to destroy reputations and silence critics of the elite power-brokers who fund them.
