Ask HN: Where can I find public domain score sheets for free?

Hi,

I wanted to play a traditional Swedish song on my piano. When looking for the score sheets, both Google and DuckDuckGo seem to be littered with big budget startups that use "SEO" and all dark patterns in the world to direct search engine traffic towards their paywall. (I'm looking at you Musescore!)

Are there any "free and not dodgy like Wikipedia" websites where one can find public domain piano score sheets?
