A Map of the Steampunk Literary Landscape

Found this interesting map of the Steampunk novel landscape.
Created by writer Louise Curtis, she writes about Steampunk on Tuesdays.
She has this to say about the map:

Yes, it’s finally here! My idea of what a map of steampunk might look like. Harangue me on my choices and omissions below! Post it wherever you like, with a link back here.
Caveat #1: This is only books (I tried to make it only novels, or at least novelists).
Caveat #2: I’m only one person. This was a big job, and I chose to oversimplify rather than make it my life’s work. Also, there are some errors. And, as you can tell, I chose to finish the map this year rather than take longer and make it bigger, prettier, and funnier. And yes, I read and write mainly young adult, which is also obvious at a glance.
Caveat #3: More is being written all the time. Tell us about your favourite steampunk in the comments!

There follows a linked list of all her Steampunk novel reviews.
Here is the map (gotta love whiteboards!):

Keep your sightglass full, your firebox trimmed and your water iced.
