United States Senate, Committee on the Judiciary, Copyright Law Revision (Senate Report No… (1975)
“ REGISTRATION AS PREREQUISITE TO CERTAIN REMEDIES The need for section 412 arises from two basic changes the bill will make in the present law: (1) Copyright registration for published works, which is useful and important to users and the public at large, would no longer be compulsory, and should therefore be induced in some practical way. (2) The great body of unpublished works now protected at common law would automatically be brought under copyright and given statutory protection. ”
