This is good - and has pointed out to me a(nother) major difference between out two great nations.
We do ban books (or at least we used to) BUT - we don't piss around at city, school district, or county level. Our moral guardians are a federal authority (and were occasionally state).
I was having a look for a definitive list of banned books but in about 1973 legislation changed. So we don't censor, we classify. But a 'Refused Classification' is effectively a ban.
The legislative change came about because a view became predominant that 'adults should read what they want to read'.
From what I've read the two books that motivated this change were 'Lady Chatterly's Lover' and 'Catcher in the Rye'.
The former was so banned that 50 years after it's publication we were banned from hearing about a case involving it.
In the latter case we ended up in the embarrassing situation of customs seizing the gift of a crateload of copies of Salinger's book donated by the US government to the Australian government.
Anyway here's the list of banned books in reverse date order
Oddly (or not) the items most often receiving 'Classification refusted' these days are computer games. There a literally hundreds banned. Not sure how successful banning something you can download is, but they do it.

is up to - but I suspect these are almost all 'at one time, but no longer banned' - I know for effect that Baise-Moi is undergoing a revival right now courtesy of Olga on Facebook.
