Remember Forever Amber a.k.a. 309 East 83rd Publishing, the rampant plagiarists? Well one tale has emerged of an author whose entire book was appropriated by these asshats, who managed to publish it before she did.
I do hope that puts pay to any notion that 309 East 83rd Publishing is in anyway legitimate. I think they need to be put out of business as soon as possible. And if they (he? she?) want me to think any different they should pay full restitution to all affected authors and prove the legal origin of any book they still offer for sale.
Although I personally would not take away the lesson that registering copyright is a necessity, unless you happen to have posted most or all or your work online prior to publication.
