Yo God! Jay
I would love to know the public school librarian's reason for banning this book? I have a Masters of Librarianship and Information Management from the University of Denver (Class of 1984) and find this quite strange.
Most libraries have copies of books like
the Bible,
the Koran,
Paradise Lost and all kinds of others with religious themes.
Maybe this was an Elementary School Library and the librarian just thought this was too advanced for that age group? Or maybe a librarian on a power trip? That happens too but is a librarian's or some clique of librarians' choices which usually has nothing to do with wider policies, fairness, censorship, or anything else that just people following selfish interests.
