A recent answer to a question here about the legality of publishing a work for which the copyright owner cannot be found mentions
If the owner has no legal heirs, in most jurisdictions the property escheats to the government (in the US to the state government).
How do U.S. state governments normally deal with such intellectual property whose copyright has escheated to the state? Do they auction it off? Release it as public domain? Something else?
I know that U.S. federal government publications are normally released into the public domain, but I'm not sure if that applies to the state governments at all or if it would apply in the case of orphaned works that have escheated to the state.
