= Public domain scientific paper by year
Here we list public domain <academic papers>. They must be public domain in the country of origin, not just the <US>, which had generally less stringent timings with the 95 year after publication rule rather than life + 70, which often ends up being publication + 110/120. Once these are reached, they may be upload to <Wikimedia Commons>!
