If you're distributing, sharing, licensing, or selling your works, *timely”* (IMMEDIATELY) register them with the US Copyright Office (USCO), and certainly no later than three-months of their first-date of publication to preserve your full legal rights. It’s NOT necessarily your un-published manuscript (work) or RAW/original file that helps prove your copyright creation. Instead, a federal judge MUST see your issued copyright *“Certificate of Registration”* that the USCO will mail you - your Certificate is your *“presumptive legal evidence”* of your copyright authorship (creation) & copyright ownership claims. Your *Effected Date of Registration,”* that will be listed on your Certificate, will be your official US government (USCO) date stamp, aka, your copyright PROOF.
