I am puzzled by a scanned book I found on archive.org,
Startling Stories Vol7 No1 (Jan 1942). According to The Internet Archive description: "Copyright was issued in 1941, but no renewal was recorded, this work is Public Domain under Rule 6 of the Copyright Statutes of the United States."
BUT, the issue contains "Christmas on Ganymede" by Isaac Asimov. That has been republished
numerous times. So what's the deal? Has The Internet Archive made a mistake? Is the scan out of copyright but the etext in copyright? Is "Christmas on Ganymede" only legal-ish if it's part of that group of stories?
Copyright law is so confusing...
