Author and cartoonist Art Spiegelman is familiar with the hysteria surrounding certain library books. In today's episode, he tells NPR's Scott Simon about how comic book burnings during his childhood in the 1950s weren't all that different from book bans taking place across the country today. Spiegelman says that though they tackled difficult subjects, he found then – and continues to find today – great emotional power in comics, such as his reissued collection Breakdowns. And he says he's felt deeply unsettled by the ongoing challenges against these kinds of books.
