My recent concerns about protecting my books against assorted forms of piracy are increasing at more news of electronic innovations. First there were Google Books, somewhat restricted by publishers fighting to protect copyrights, then there was an outfit that libraries subscribe to for downloads of novels, next Kindle 2 added audio capacity (thereby cancelling an author's option to sell audio rights), and today I came across SCRIB'D, which appears to be a member web site where people can upload and download novels and other books for free.
Does anyone know anything about this and how it works?
