I'm not exactly sure where to look. Nothing at feedbooks. The Kindle version and the two linked from the on-line books page are
abridged editions. Gutenberg's doesn't say if it's unabridged. It's at least in HTML and retains some formatting, but it would be great to download a copy in which somebody else had made sure the "family tree"-type charts displayed OK on an eInk device. Manybooks butchers the Gutenberg edition by destroying the "trees" and endnote links.
Is there one out there, or should I do it myself?
