I've been mostly making notes on my kindle and then other random stuff (highlighted pdf files, text files, screenshots, etc).
Is there any "modern" solution for handling book notes/excerpts I'm not aware of?
Best overview of the landscape I've seen so far is here [0]
Personally I've been using a combination of Roam Research [1] and Readwise [2]. Used Notion [3] for a while but it's very hard to tag data.
I have a broad notebook called "Books" and then tag each post with relevant topics. As you continue to add to evernote in other domains with similar tags you can aggregate all the information into one place.
You can even make a tag of the bookname and go from there.
Bear is a cheaper alternative but i personally didn't like it too much.
