What I was initially interested in is how many authors have had collector's editions produced. But I think that question is a bit irrelevant because of the nature of Australian indie press and also of genre publishing. Before about 3 or 4 years ago, the entire printing/publishing model was completely different. POD didn't exist for example.
But there are some interesting things about the lists above.
ETA: Note - this was written prior to additions. As this post is evolving, I leave and reanalyse at the end.
Female authors get collected at 1:4 of male authors in specfic in Australia.
25% ... that's a number we've seen before.
Secondly, only three female Australian authors have been collected more than once. And no points for guessing who they are - Lanagan, Sussex and Love. Warren's collection was reprinted in USA with an extra story (as The Glass Woman) but I haven't included that here.
Ten male authors have been collected more than once which is close to the maths of overall women:men (1:4). And they are - Broderick, Brown, Chandler, Dann, Dedman, Dowling, Egan, Haines, Hood, Williams.
In both cases, authors with multiple collections are all names that come to the top of any list of Australian specfic authors.
