If your hobby is reading, especially those works by former writers like Mark Twain, or literature like William Shakespeare or autobiography/biography, I believe you'll like this site.

On this site you read thousands of books with various topics (mostly English literature). But I found that some Chinese Literatures are also there, like Confucius Analects.
But the pity is that there is not search engine on the site.
