What I like about being able to get the short stories in eformat is that many of them are stories I read long ago. They were in Asimov's, FSF, Analog, etc. But then, unless they are included in an anthology, they sort of vanish. Even the Nebula and Hugo winners become impossible to find again after a while. But now, thanks to ebooks, those golden oldies are re-surfacing. I have been able to re-read many of the stories I enjoyed so long ago.
The short stories are where a lot of the basic ideas are formed. A single incident, the definition of a short story, is often later expanded into a novel or series. Like I said earlier, I LOVE SHORT STORIES!
