Which Is More Reliable Books Or Internet?

I think Books are more reliable because anyone can write something up and the upload it on some website but it takes much more hard work to publish an entire book. You need to do research, proof read it and of course get it published and that needs money. Only people who are serious enough to do actual research on a topic or when they are confident that the book is worth all the efforts only then they think about publishing. It is much easier to just copy paste some one else’s work and hide your real identity on the internet which people don’t usually do in books. But in the end the authenticity depends on the writer not the medium, is the information is given by a credible source even if its on the internet has the same trustworthiness.
