"list" is probably harsh, but I've had good luck trawling through the GitHub topics to find such things: https://github.com/search?p=1&q=topic%3Apdf&type=Repositorie...

Makes me miss freshmeat.net which would have been my answer a few years ago (freshcode.club just isn't the same, although bless them for trying)

Circa 25 years ago I was newly wed and my wife happened to be watching over my shoulder as I looked up something online. I started typing "fr" and "freshmeat.net" came up as a possible completion.

She was, to put it mildly, immediately suspicious of my browsing habits.
