Zettelkasten is a method in which you write down your thoughts in notes, tag, and connect them over time. This method was used by the sociologist Niklas Luhmann, which helped him to be extremely prolific in his field. During his 40 years of research, he published more than 70 books and over 400 scholarly articles.
I appreciated this method and I use it when I'm studying some topic or have some insight. If you want to know more about it, I recommend this post, that explains the history, advantages, and how to create a Zettelkasten for you. I've also written some notes about this method.
My notes usually have 4 main parts:
- Notes: they're my notes about the topic.
- Questions: they're questions I made while studying the topic to perform a metacognitive reading.
- References: these are references that I consulted to write the notes.
- Backlinks: links to other notes that referred to the current note.
