Nineteen Eighty-Four is more interesting, apparently, there are hundreds of vendors selling it on taobao.com, including the Xinhua which was started/owned/managed by the Communist Party of China.

(In all due deference, Capitalist Realism is a very anti-capitalist argument, so...)
Only once has customs had the slightest look at our bags and that was when the airline left them behind and we had to pick them up later. I was wheeling out a cart with 4 checked bags, no carryons and that drew the interest of the customs guy. The entry stamp two days earlier also drew his interest. He started running the bags through his x-ray, at that point my wife caught up and explained what had happened (she's a native speaker, I figured it was easier to leave any discussion to her) and that was the end of it. Nothing was ever opened.
Even the day my wife set off a nuke alarm at customs produced no response. (She had set off a previous alarm also, which was resolved with a short discussion. They never checked what the actual radiation source was and the card from the lab that explained why she was hot was sitting at home in the pocket of the jacket she didn't wear.)
Now, if my employer was some big company I would be concerned with espionage but that's all. Since my employer doesn't do anything remotely of interest to the Chinese I don't worry about it. Besides, we stay with relatives, my laptop has never seen a Chinese hotel room.
However if you brought any book that attacks current government, for example books about the 64 event, you would be in very big trouble.
You seriously believe that she is less influential than a few books? If Chai Lin is allowed to enter and stay in China, what is the point stopping a few books?
Its an only state where during my travels on the way out of the country (Russia here) in addition to usual security scan and passport control you have an additional booth maned with rusia official/military personel only judging if they can let you out. Again: this was in addition to passport control due to destination etc.

P.s. Overall Russia experience was very good and eyes opening (comparing to what you get from media)
My point is perhaps you were profiled to your benefit as well.
Edit: I'm from the US.
I still visit semi-regularly (once a year, approximately) and my observations remain valid now as then (for me at least).
Same goes for my experiences going into and coming out of Russia, for that matter.
