Spycatcher isn't banerned now. They overturned it when they realised people were buying abroad anyway.
James and The Giant Peach was banned because it, apparently encourage disobedience towards authority.
The Wiki site is the one I looked at initially and it is indeed interesting. I subsequently found out about the American Libraries Association 'banned books' week, which highlighted many books which were banned for various reasons - Judy Blume being the most banned author.
It make me happy and indeed proud to be British because of the lack of banned books in 21st century Britain.
Some books are unavailable, but not banned.
It's a shame the Americans aren't as free as we are.
