Jeff Bezos is the world’s biggest bookseller. You can buy anything on Amazon: Hitler’s Mein Kampf, the polemics of Lenin and Mao, the poetry of Amanda Gorman. Amazon sells and ships independently published editions of The Protocols of the Elders of Zion (5-star readers’ rating) and 100%-cotton “I heart The Protocols of the Elders of Zion” T-shirts (“Great for birthdays, Christmas, Hanukkah, Valentine’s Day, anniversaries, puppy, a lover, partner, daughter, or even a pet poodle”). For a few days in mid-April, however, you could not buy the new translation of Jean Raspail’s 1973 novel The Camp of the Saints.
