This has been a sub-topic in the Book Discussion Thread for the last few days, but one I feel passionately about, and I don't feel that giving a quick list is doing enough to really sell these stories.

Short stories are a delicate and useful medium for writers, but readership is low because they are difficult to publish, except in fast-vanishing literary magazines, anthologies, or collections. But the commitment level is low, and usually these stories are widely available (thank you, internet) so there's no excuse to not indulge a little bit.

I'm sticking to one story per author, but I might slip in hints about other works by the same person.
