Ok.. I've hooked my roommate on the Liaden Universe. She's worked her way through nearly all the novels and has started on the short stories/chap books.
We've pretty much got the reading order down for the novels, but she asked me last night if there was a reading order to the short stories.
Wikipedia has a listing of the short stories in what I assume is published order here:
but I've yet to find anything listed chronologically. I'm just anal enough to attempt a list if there's nothing else available.
