Alan Moore's Neonomicon challenged in South Carolina.
From WSPA:
Recently, the teen found the book, "Neonomicon", in the library's adult section and thought it would be a real page turner. Kids above the age of 13 can check out books in the adult section, if they have their parents' permission. "It looked like a murder mystery comic book to me," recalls Carrie Gaske. "It looked like a child's book. I flipped through it, and thought it was ok for her to check out."
My emphasis. Because it sounds a whole lot like this complainant is suggesting that either A) everything in the adult section should conform to her idea of what is appropriate for her fourteen-year-old daughter, or B) that all books should have a rating. (The ratings argument comes up later on in the article.)
Also, the library system doesn't appear to be into the whole 'innocent-until-proven-guilty' thing—both copies have been pulled off of the shelves until the challenge is resolved.
