FYI regarding Flatland:
What Froide is posting here and on other
threads is Open Road's free classic ebook of the day. They've got a daily email "Early Bird Books" newsletter (
today's newsletter) with sale books and a free classic, with links to their specific books at all of the major stores.
I took a quick look through the first half of their edition of Flatland, but I didn't see any illustrations

. Other than that, their editions seem pretty well done.
