The librarian sounds dreadful but...we also have to take into account that they have some things working against them. So, let's say Mrs. X gives HP to an interested 1st grader and that child starts to read it right away and then takes it home to his ultra conservative, devoutly religious family. The same family that heard in church on Sunday that witchcraft is a sin. The family freaks out, tells everyone, writes letters, places calls, goes to the school board, etc.
I go to my children's teachers and librarian every single year and give blanket permission for them to read anything they would like. It saves heartache for everyone.
