I wish he'd gotten into more of the detail of the research and index card making here as that's where most of the work lies. He does show some of his process of laying out and organizing the cards into some sort of sections using 1/3 cut tabbed cards. This is where his system diverges wildly from Luhmann's. He's now got to go through all the cards and do some additional re-reading and organizational work to put them into some sort of order. Luhmann did this as he went linking ideas and organizing them up front. This upfront work makes the back side of laying things out and writing/editing so much easier. It likely also makes one more creative as one is regularly revisiting ideas, juxtaposing them, and potentially generating new ones along the way rather than waiting until the organization stage to have some of this new material "fall out".
