Which type of note is ZK for the subject study?

If I wanted to study a subject, for example, software components. I’ll also refer to a number of online articles or PDF files, and then extract highlights from those articles on the subject, but may not have any ideas of my own.

I want to apply the ZK methodology and even evergreen notes. Typically, the literature-note will extract reading notes, but is it more focused on one article or book than on multiple sources? A subject-oriented excerpt like this, with reference to multiple sources, would belong to a fleeting-note or a literature-note?

I’ve also asked the same question on Reddit, and I’ve had a lot of great comments from Reddit.
