The artbook and digital comic are both online bonuses. If the webpages are ever gone, we lose them. I wish we could download them as E-books or something. Yes, there are video clips in them, but I've seen E-books with video clips that can be viewed offline. In fact, I've bought one such E-book, which was made by a digital publisher named Yudu. I believe Adobe PDFs can contain video clips and other multimedia content too.
