Despite recommendations by a library committee that the book be retained, Alan Moore’s Neonomicon was pulled from library shelves in Greenville, South Carolina. The library services director who ultimately made the decision called the book "disgusting" in an interview with The Greenville Times. KRRP Project Coordinator Acacia O’Connor told The Guardian (UK) that readers "have the right to make up their own minds about whether they want to read the book and not have their choices dictated by the subjective views of others."
The challenge was first lodged in the spring of 2012. At that time, NCAC, the American Booksellers Foundation for Free Expression and the Comic Book Legal Defense Fund wrote a letter to the library director defending the work and urging her to retain the book. You can read that letter here.
