Good work. I think between this book and the Digital Zettelkasten book I see some limitiations. For example, it seems that the focus is generally on having a specific field of study that you are working with. I know this can work in the real world for some people, but if you aren't really reading or working towards writing a paper for your job, it isn't likely to be all that useful.

I do feel, however, taht Chapter 13 is pretty weak. It's really just covering the same material that you've spent twelve chapters reading. that chapter could have been condensed, and/or possibly combined with chapter 14 - which is about making the process a habit.

But still, there are a lot of things that are interesting aabout this book. Possibly the best part is "Chapter 15" in the appendix: a look at Luhmann's Zettlekasten -- that actually answers some of the questions that the main portion of the text cannot answer.
