I put together a list of all the short fiction I've had in print, mostly so I could keep track of things myself. However, if anyone is feeling like a monomaniac completionist, look upon my works, as they say:

I haven't included the Shadows of the Apt fiction that only turns up in the Tales of the Apt collections, as that should be fairly easy to track down. For reference those collections are: Spoils of War, A Time for Grief, For Love of Distant Shores and (with a number of other authors) The Scent of Tears.
