Reading a collection of short fiction from any given author is always a mixed bag. Same goes for an anthology of works by different authors centered around a certain theme or category. You might like some and some, well, they round out the collection.
But when you have a “Best of” collection, especially one curated by another well known writer or editor, well then, that’s a great way to start a good library. And that’s what Tor.com talks about in this article featuring A Survey of Some of the Best Science Fiction Ever Published (Thanks to Judy-Lynn Del Rey). While I’ve read some of these, and own several, a bunch more are going on my wish list.
