No, books are not more reliable than internet because in formation on the internet is more compactly stored. Most of the time the info is uploded exactly at the time of the real event happening, but books take a long time to be written, and most of the info in them is copied from the internet itself. Also, the internet being so loaded with traffic, more than the book sales itself, all the publishers on the inernet are more under pressure of checking that the info is reliable. So they write more correct info on the net, as it has to be seen by thousands.
