What happened is that the board approved a motion to remove Maus from the list of prescribed materials for the 8th grade unit on the Holocaust. Lord of the Rings isn't on that list either. Neither book has been "banned".
> Prohibiting books from being added to a curriculum is what banning is.
The board didn't "prohibit" anything from being added to the curriculum. They are the ones responsible for the curriculum and they simply removed Maus from it. As noted in the meeting, they could add it back at any time if they choose.
