Angel asks about registering his multiple copyrights under a single folio of works.
This video provides my answer:
The short answer is yes, it's often possible to register multiple works together as a folio. But, it's not always a very good idea.
Some recent court rulings seem to suggest that when multiple works within a folio are infringed, the plaintiff may only recover one award of damages. Also, if it work isn't registered within three months of its original publication, The plaintiff will not be entitled to recover attorneys fees, nor collect statutory damages. So, registering your works as a group could really be shooting oneself in the foot.
