Can anyone provide any definitive information whether a work from 1926 is in public domain or not? I'm looking at Aeschylus' works which were published in 1926. According to copyright law works published between 1923 and 1963 would be in the public domain if they were not renewed. So far it seems there are a few ways to check whether a work was renewed or not, but I couldn't find anything that I would consider 99% reliable. Anyone able to provide any further info?
My assumption would be that this particular work would not have been renewed since there are at least two newer versions of it, the Page edition being the most recent. My goal has been to provide the best public domain texts possible of classical Greek texts and I would hope to offer Aeschylus' works in the near future, but I want to proceed legally.
