Registration is recommended for a number of reasons.
You may wish to have your copyright be a matter of public record. If the work is registered within five years of publication, it is considered prima facie evidence in a court of law. In other words, the burden of proof is on the infringer. And registration allows you to register the work with the U.S. Customs Service to prevent the importation of the work in the case of infringement. That said, this is most important to creators of unpublished or self-published work.
