All I'm doing is trying to remember where I'd be likely to have read the same story myself. If it's not in the big Asimov & Greenberg anthology (they've done a lot together, but there's only one *big* one, called something bland like "Greatest SF of 20th Century" or something, originally only two volumes, but now many, many), then the only other likely site would be a more slender hardback anthology edited by Robert Silverberg -- but if that's so, then *all* the stories would have been thematically linked, probably about time travel. He did a whole series of theme-anthologies (one of the best was on spooky children, had "It's a Good Thing," among others -- you know the one).
Apparently that series is out of print (I used to check 'em out of my library), since I can't find any of them on Amazon.
I did find some very useful recommendations and, even better, "Listmania" lists on this page. But nothing I can definitely say is it. |
