You might also want to go to the
UPLOAD section and inform everyone there - in the
eBooks We're Working On section - it's a
STICKY and is at the top of that page. The Sticky means that the thread is always there for us.
You'll find putting books together fun, frustrating, and rewarding.
I almost always put books together that I want to read, so it's really rewarding to have these books -
and others from so many fine contributors - on my Reader.
I actually have
287 titles listed on my Reader (I don't really recommend this), but thanks to Haryy

, I actually have more
BOOKS loaded. (This is because of the omnibus titles.)
Anyway, go to that section I mentioned, and I feel you'll reach a larger audience for your subject.
Have fun!!

P.S.: In my opinion duplicate work is ok, because your conversion of that title(s) is going to reflect how
YOU would like that title to look like. It may be in the art you select (if any), and in the way you format your book. I wouldn't worry about that.
I look forward to your first book by
Twain / Clemens.
Hint: Always try first with an HTML file to work with.
