US copyright expiry
Hi, do you know anything about US copyright expiry? There is a discussion going on at en-WP here and I know RAN has uploaded a lot of stuff here with the rationale that copyright has not been renewed but, it seems, has not actually done any due diligence regarding that claim. Instead, he has made a presumption.
Is the IP correct in that discussion? Can it be pinned down in many cases?
I don't mind where you reply - here, my talk page on en-WP, the discussion itself - and I realise that you may not know the answer. I find a lot of this copyright stuff far too arcane for my brain. - Sitush (talk) 20:02, 16 June 2018 (UTC)
