This Oct. 1 through Oct. 7 is National Banned Books Week. It’s an opportunity to celebrate our freedom to read — a uniquely American right guaranteed under the First Amendment. It’s also a chance to reflect upon the long history of challenges to that right. I remember when, in the early 2000s, the Harry Potter books came under fire in certain parts of the country because, as detractors argued, they were promoting witchcraft and indoctrinating young minds to the occult.
