people on the internet just may post up rumours and none of it is true but books have facts in them, reliable facts. As a general rule, books are a more trustworthy source than the Internet –but that doesn’t mean that the Internet can’t be reliable too!
Some books are trash, but for the most part getting a book to publication requires a high level of talent, commitment, and research on the part of the writer. Anyone can publish anything they want to on the Internet. There is no requirement of truth or reliabilty, and the Internet has the added benefit of complete anonymity, so people can commit libel without reprisal.
