These days all publishers are worried about their rights and the books are locked in, which is especially problematic in this digital age.

It can’t be shared with our friends even if we bought it with our hard earned cash. People who realize this come forward and fight against DRM these days to support free sharing. Because… >only free sharing promotes free knowledge And now Packt publishing is giving an offer for today. Check it out!
