Dear Rich: I self-published a novel in September 2013. Is it too late to register my book with the Library on Congress? No, you (or your estate) can register any time that the work is protected (your life plus 70 years). If you register before an infringement occurs you can elect statutory damages and may be entitled to attorney fees. Also, you get a neat certificate. Although registration has its benefits, keep in mind that it is not a requirement for copyright protection.
