My question isn't really related to TCS itself, it's more about technical and informational equipment of a computer scientist.
There is a website SafariBooksOnline by O'Reilly Media where anyone can read lots of books about IT online for a per-month payment. That's why you don't need to buy expensive books if you want just to run through a chapter and look through the content briefly. And you still can read it all if you feel yourself comfortable reading large book from a screen being constantly connected to the Internet.
Are there such websites with TCS books or science books in general?
