"In Lake Travis ISD, all copies have been removed from library shelves. And just last week, Keller ISD, north of Fort Worth, restricted access to Out of Darkness in all high school libraries, citing the book’s “violence and difficult imagery.” Students in the district must ask a librarian for the book and show proof of parental consent."

I see your concern that a district choosing not to stock a book is not news, but in this case it sounds like the book was available and used in the curriculum in many districts for the past 6 years, and then only banned this year after the video by Kara Bell was publicized.
