How to keep track of things you have read?

Hi. I have been thinking about keeping track of read books, articles, comments, etc. and was wondering if anyone had some great setup/software. Something that lets you keep track of notes and highlights, potentially tag to easily find books about a subject. Something that's made for going back and gathering information from them, probably not just like a bookshelf. Surely researchers or students have something like this, needing to keep track quite like I'm trying to describe.

Thank you!
