Biggest so far (and biggest on SE at 1.2m words) has been Samuel Pepys’ Diary: https://standardebooks.org/ebooks/samuel-pepys/the-diary
That book is more than 2600 pages! How long did that take?

Typically, Standard Ebooks will try to avoid OCR unless it’s something that’s missing from Gutenberg.
(If you started some sort of AMA here I'm sure it would be successful.)
Are there any plans to support non-English ebooks as well?
Edit: Regarding non-English ebooks, I was thinking about books like "Der Vogelflug als Grundlage der Fliegekunst" (Birdflight As The Basis Of Aviation) by Otto Lilienthal (https://www.gutenberg.org/ebooks/54565). It's a fantastic book with nice hand-drawn illustrations, and it would deserve being presented/typeset in a beautiful way. Currently available ebooks are mostly bad.
For those who loved the Andrew Lang rainbow-color fairy tale books, Lang also published a volume of The Arabian Nights, not a translation but a recounting of selected tales. I encountered the Richard Burton commodious 3-volume set as a child. It's amazing that nobody at the time thought to proctor my reading choice, given the racism, misogyny, salaciousness, naughty illustrations, everything delivered in such a matter-of-fact tone and just laid out there. To read it cover-to-cover is actually not terribly fun. There's lots of little folk tale snippets, fables, poetry, and Burton footnoted the hell out of everything.
