Yes sure! For your first question, it depends on the source, for example a book or a paper usually is a note because i like to resume or quote interestings idea or discoverings from them. Blog posts and news rarely are notes but usually they’re put at the bottom of a note or link with title or one-two line description.

Books, video essays and so on are located inside a directory of resources. I usually add these resource notes as additional sources at the bottom of the topic notes, and/or quote what I find interesting fron the source.

Every note in my vault is tagged, this helps to find “hidden” connections between notes. As said before, not using systems like atomic/evergreen notes with strong atomization of content, full text search is essential for retrieving in my system. I use different vaults only if I need a strong separation between content, for example I have one for study/work, one for more intimate and general purpose stuff and one for preparing DnD campains.

Sorry for my english. Here’s what i usually do:

• kanban as read-list and task tracking
• introductive note to a topic with backlinks to other notes (subtopics)
• a directory with all the subtopics notes, backlink to index note.

I don’t like atomic notes or Zetelkastenn methods enough, but be sure to check these methods. If you’re more visual, then you may use the canva plugin.

The best system is subjective, try different things and find what works for you.
