Hi, I’m looking for a good library software for managing notes for university classes. Let’s say for exsample that I see “electrochemistry” in a book and I forgot the basic principles of electrochemistry, but I have some very understandable notes with drawings that explain electrochemistry easily which I can retrieve from a library. Any ideas for a good way to manage these notes and drwaings? I attached a file that kind of shows the idea I'm looking for. I'm not a programmer, so a someqhat easy-to-manage library would be nice.
