Re: Do books need to be approved as well?
You've misread the link:
Jane Eyre /was/ banned, during the Cultural Revolution. That was a long time ago.
Alice in Wonderland /was/ banned - but by the Nationalists of the KMT, when they were still ruling parts of the mainland, not the Communists of the CCP.
See for yourself, they're all available today at Amazon:

I've seen paper censorship at work when living in Beijing, in 2009. I was subscribed to Time Magazine, which was delivered through Hong Kong. In June, I got an issue which had a different wrapping than the usual. When I opened it, I quickly noticed that one page was missing, the leaf had been neatly cut out in the middle of the magazine, leaving only the page on the other side of the staples. Sure enough, from the table of contents, that was the page of an article about the 30 year anniversary of the Tian'anmen square events.
