Local comics historian Warren Bernard (friend of ComicsDC, SPX grand poobah) volunteers at the Library of Congress' prints and photos division, identifying editorial cartoons and topics for them, but he snuck over to the building next door to research and write an article on Fredric Wertham's anti-comics crusade for the Comics Journal #302. Warren's kindly convinced the journal to put his research material online.
