Dear Rich: I just created a small, self-published book of photographs to sell. I had previously registered with the Copyright Office all of the photographs in the book. Is there any reason for me to now register the book itself? Unless there's additional material such as text, illustrations, or a forward and you're concerned about someone stealing that, we can't see any reason to register the book of photos. As you may know, registration doesn't establish copyright (that's automatic), but it does provide you with additional benefits in the event that you're chasing an infringer. BTW, here's a video we prepared on how to register a group of photos.
