Whoa, SE looks incredible. Thanks for your work on that!
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.
Sorry, no. Like I said in another comment, a large part of what makes SE good is our manual of style, which is really just applicable to English works. If you want to use the toolchain to produce a novel in another language feel free (removing our logo and name, of course).
Nearly two years, but I took a bunch of time out to work on smaller pieces. The biggest problem was that Gutenberg had only transcribed about a third of the footnotes, so I spent a long time adding the remaining ones back in.
I had a chat with Phil after I finished, and he sent over a list of transcription problems with Gutenberg that I’d missed which was very kind. But apart from that, no direct collaboration.
Biggest so far (and biggest on SE at 1.2m words) has been Samuel Pepys’ Diary: https://standardebooks.org/ebooks/samuel-pepys/the-diary
