With the Zettelkasten process, it is often said that we write down literature notes that correspond to the papers/books first, and then organize them into linked permanent notes.
One issue is that this implies a linear reading process – one starts a paper/book, take literature notes, and incorporate the knowledge into the permanent notes by making new permanent notes and link them with existing ones, and move on to the next paper/book.
My reading process tends to be highly non-linear. With a topic at hand, I would read the relevant parts of a dozen papers and books and take notes. This result in highly incomprehensible literature notes, especially for books, because I typically am only interested in the topics in the books that add to the current topic. This happens with papers too, when what interests me is not the main topic of the paper.
In a way, the Zettelkasten method is supposed to promote such circular reading process, and so I am probably doing something incorrectly.
What is the best practice when it comes to topic-centric, non-linear reading?
