I know most of this stuff for Canada and the Canadian Copyright Act (or at least where to find it...), but can anyone point me to any useful information for the US on determining a) whether a photograph is still copyright or has passed into public domain (it's complicated in Canada depending on various things...) b) what to do if you can't track down the copyright owner (say the photographer or their heirs) on an old photograph that someone wants to reproduce. I know that in some jurisdiction there are a "reasonable" set of hoops that can be jumped through if the owner can't be found or identified. thanks tim ========================================================= Important Subscriber Information: The Museum-L FAQ file is located at http://www.finalchapter.com/museum-l-faq/ .
