It's all weird and confusing. But I guess can make myself a nice clean ePub with a clean conscience
All of science fiction was pretty much obscure, niche-market stories. Even today, science fiction is considered not-really-literature in a lot of places.
And prolific authors who didn't keep extensive records of what they published where, were likely to not update the copyright; the copyright office didn't send out "your copyright is about to expire!" notices. Besides, how much income would Asimov expect to make, in 1968, on a story he published in 1941?
