Actually Sorcha is correct

'Were any books censored banned? June Pinell-Stephens, chairwoman of the Alaska Library Association's Intellectual Freedom Committee since 1984, checked her files Wednesday and came up empty-handed'

the Anchorage Daily News Sept 4th

although .....

'Back in 1996, when she first became mayor, Sarah Palin asked the city librarian if she would be all right with censoring library books should she be asked to do so.

According to news coverage at the time, the librarian said she would definitely not be all right with it. A few months later, the librarian, Mary Ellen Emmons, got a letter from Palin telling her she was going to be fired.
The censorship issue was not mentioned as a reason for the firing. The letter just said the new mayor felt Emmons didn't fully support her and had to go.

After a wave of public support for her, Palin relented and let Emmons keep her job.'
