Rule of Thumb, US Copyright
What is the general guideline for a book entering the PD in the US? I would like to test my hand at a making some epubs based on older books that I cannot locate on Gütenberg Project, but do not wish to make then public if it is unlawful to do so.
IN particular, I am looking at The Richest Man in Babylon by George Clason. My copy says it was first published in 1926.
Thank you in advance.
