The <a href="https://standardebooks.org/" rel="nofollow">https://standardebooks.org/</a> project has been rebuilding ebooks (open ePUB format) with an eye on quality and readability on mobiles/tablets (fonts, copyedit, etc.) which might be of interest, all books and the website revision are tracked in git.
I wrote a technical comparison between various public domain eBook projects:<p><a href="https://dave.autonoma.ca/blog/2020/04/11/project-gutenberg-projects/" rel="nofollow">https://dave.autonoma.ca/blog/2020/04/11/project-gutenberg-p...</a>
They’re probably going to have to change their name to something that does not have “git” in it: <a href="https://public-inbox.org/git/20170202022655.2jwvudhvo4hmueaw@sigill.intra.peff.net/" rel="nofollow">https://public-inbox.org/git/20170202022655.2jwvudhvo4hmueaw...</a>
This looks like a subset of Project Gutenberg?<p>The Girl from Alsace in Gitenberg: <a href="https://www.gitenberg.org/book/35926" rel="nofollow">https://www.gitenberg.org/book/35926</a><p>The Girl from Alsace in Gutenberg:
<a href="http://www.gutenberg.org/ebooks/35926" rel="nofollow">http://www.gutenberg.org/ebooks/35926</a><p>The numbers are even the same which seems suspicious. Hmmm.
You might be more familiar with another project the Free Ebook Foundation maintains: <a href="https://github.com/EbookFoundation/free-programming-books/" rel="nofollow">https://github.com/EbookFoundation/free-programming-books/</a> Which is one of the top-10 repos on github by number of stars.
I like how they're able to accurately tag translators vs original authors, e.g. <a href="https://github.com/GITenberg/The-History-of-the-Peloponnesian-War_7142/blob/master/metadata.yaml" rel="nofollow">https://github.com/GITenberg/The-History-of-the-Peloponnesia...</a>
