PD rules are INCREDIBLY convoluted and rarely make any kind of sense. There's not -- that I know of -- a big list that's easy to check. You have to track down publishing date, author death date, and then start digging through Mickey Mouse exceptions and start doing all kinds of math, and at the end of the day, it's still a crapshoot.
I guess I haven't really thought things through. But maybe somebody will make that list.
