Hi all, I have a number of MapArt/Canadian Cartographics Corporation maps in hand, ordered at the very beginning of the year, that all read (c)2018. I can and will put that in 264 _4. What are the rules for handling obviously impossible publications dates in 264 _1? This isn't necessarily a map-specific cataloguing question, but it would be good to know!
