Start here: http://www.google.com.au/search?q=free+books+online&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a Otherwise do a search for "free books online". Make sure you set your search criteria to "English". I see you are in China. To get a full search you will need a proxy to neutralize the blocking there.
