Pre-1922 is *definitely* in the public domain in the US; between 1923 and 1963 is maybe (but if it's well-known today, that's probably because it was renewed); post-1963 is PD only by bureaucratic glitch or author's intentional release.
And there are Creative Commons/open source texts that could be reformatted for MR readers; a lot of those are released by the author/publisher in PDF format and need reworking to be easily readable on most devices.
You're correct, of course. However, it is difficult to ascertain whether copyright was renewed. Although for MR purposes it is not important as it needs to be public domain in Canada only.
I was commenting that it is harder for US residents to add to the list when we are mostly restricted to pre-1923. And much is already available on MR.
Starting Jan 1st published works of pre-1961 deceased authors enter Canada's public domain. They have much more available to them and can legally upload to MR.
