Parents complain about Twilight
Twilight author Stephenie Meyer has earned a place high on the list of books most complained about by US parents and educators.
Meyer's multimillion-selling Twilight series was ranked No 5 on the annual report of "challenged books" released by the American Library Association.
Her stories of vampires and teen romance - which have so far been made into three films starring Robert Pattinson, Kristen Stewart and Taylor Lautner - have been criticised for sexual content, and a library association official also thinks that the series reflects general unease about supernatural stories.
"Vampire novels have been a target for years and the Twilight books are so immensely popular that a lot of the concerns people have had about vampires are focused on her books," said Barbara Jones, director of the association's Office for Intellectual Freedom.
Christian groups for years have protested the themes of wizardry in Rowling's books, which don't appear on the current top 10.
Topping the 2009 chart was Lauren Myracle's IM series, novels told through instant messages that have been criticised for nudity, language and drug references.
The ALA recorded 460 challenges in 2009, a drop from 513 the year before, and 81 books actually being removed. The ALA defines a challenge as a "formal, written complaint filed with a library or school requesting that materials be removed because of content or appropriateness".
For every challenge tallied, about four or five end up unreported, according to the ALA.
