With the availability of cheap scanners, cheap mass storage devices, and the Internet, for the non-corporate creator of Intellectual Property, copyright is worthless.
There are two bit torents that together contain over 500 magic books from Corinda to Chuck Hickok to ten titles from Stephen Minch...just about everything you'd need....thousands of dollars worth of material, available for a free download to anyone with an Internet connection.
I've spoken with the local head of the FBI squad in charge of copyright enforcement. He was quite candid. For the FBI to become involved the loss would have to be in the hundreds of thousands, if not millions of dollars.
Since all the victims are small publishers all over the US, Canada, the UK, etc., the losses are spread out, diluted to the point that the FBI cannot bother with the case. The agent told me that if I worked in a bank and managed to steal under $200,000 it was unlikely that the FBI would become involved, so these cases are well below the radar.
So, figure there's little to no protection for anything you produce either in print, in video or audio. It can all be digitized and spread around the world for nothing in a matter of seconds. Sad, but now a fact of life.
