Suppose the author aggregated information from many doctors and wrote it down an ebook? And what makes your doctor the authority on sleep? They inevitably get their information from scientific studies not conducted by themselves, and the author of an ebook can do the exact same thing. There's no reason to disparage the ebook just because it doesn't look like the conventional form of authority.
