Oh, there are lots of problems with that list; several sections of it have weird sampling anomalies, and I found a few factual errors in it, too. ("The Tachypomp" isn't about what they say it's about at all; they seem to have confused it with some other story.)

Le Guin is mentioned, just not in that section.

I think it may have been compiled from reader-submitted odds and ends with varying degrees of detail.
