Yeah there is very little info on it that I can find. I found the Wikipedia Entry, a couple of mentions of it in texts about early sci-fi and feminist movement.
Nothing on Distributed Proofreaders or Gutenberg.
Found it mentioned here:

as well as on Internet Speculative Fiction Database:

Google books brings up mentions of the original release announcement in NYTimes, and in Publishers Weekly. Jstor brings up the mentions in a couple of academic papers.
No copies that I have found on the Internet Archive.
It is well and truly a rare book!
@Nohmi- It is always nice when a rare book gets digitized and made available for people to read! What book were you looking for?
