From the Boston Globe:
But last month, students found that their favorite series had "disapparated" from the school library, after St. Joseph's pastor, the Rev. Ron Barker, removed the books, declaring that the themes of witchcraft and sorcery were inappropriate for a Catholic school.
"He said that he thought most children were strong enough to resist the temptation," said one mother who asked that her name not be used because she did not want her family to be singled out. "But he said it's his job to protect the weak and the strong."
Sadly, their library catalog doesn't appear to be available online. I'd love to take a look.
