Can't seem to do a search right now, but you might want to try a search for "abandoned copyright" or similar at www.copyright.gov.
The cessation of corporate form isn't the same as the dissolution or loss of property rights. A corporation is a legal fiction, usually created to gain advantages under State or federal law. When a corporation becomes a nullity property that was pushed into the corporation generally reverts or converts - it doesn't just disappear.
You need to know a bit more about the wrap-up of the corporation to know about the distribution of rights.
This could include copyrights.
