Proof of public domain

One of the most difficult thing to do is to safely determine is whether an specific intellectual property is in the public domain. Even though governments have registrar, there is no database where you can query to get a definitive answer. And, even if you think something is in the public domain, it may not be.

The PDINFO site is reference site to help identify public domain songs and public domain music . . . royalty free music you can use anywhere and any way you choose . . . performance, sing-along, film, video, advertising, business, or personal.
