Jim, registering the copyright prior to infringment makes it an up to $150,000 deal plus your attorney costs. Registering it afterward makes it a $65 deal.
If more of us would register early and whack the Publishers who are 'willfully' infringing they would start thinking twice about what they are doing.
I have averaged in the four figures in my settlements and haven't been to court yet. When a Publisher is notified and you have done your homework and registered your work prior to publication, it is a BIG deal.
Or you can be the 'good guy' and let them steal from you.
