This may be a stupid question, but why are you paying $35 and trudging through a long process to register with the US copyright office? It's jaw-droppingly unlikely that you'll ever need it. Most people don't bother.
Since this is the self-publishing forum, I think it's reasonable to expect that people self-publishing need to know how to register their copyrights. Someone going for commercial publication doesn't need to register, but someone self-publishing does.
I've seen the form, though, and am not sure why someone following the self-publishing route would need instructions to fill it out. If one plans to do all the other complex work associated with self-publishing, surely they should be capable of filling out a fairly straightforward form. Is this thread really designed to drive traffic to a blog?
