Cohen is also the author of the controversial "Curses, Hexes and Spells" (1974), which has appeared on several "banned books" lists due to its perceived advocacy of magic and witchcraft. "Curses, Hexes, and Spells" is number 73 on the American Library Association's list of the 100 Most Frequently Challenged Books of 1990–2000. Cohen said he has no problem with a parent telling his or her own child not to read the book, but "when a parent says no child should read the book, it becomes an object of censorship."
