What is the best way to register when I have hundreds of published images that I’ve taken this year?
If the images are photographs, you may register them together as a Group Registration for Published Photographs. This group registration option is available for photographs by a single photographer, published in the same calendar year, where all of the photographs in the group are owned by the same claimant. For more information on the particular eligibility requirements, please see Compendium (Third) § 1116.6.
